A tonneau cover can make a GMC Sierra 1500 bed more useful every day. It can keep luggage, tools, groceries, camping gear, and other cargo covered while helping reduce exposure to rain, road spray, dust, and direct sunlight. It can also make the contents of the bed less visible when the truck is parked.
The difficult part is finding a cover that actually matches your Sierra. GMC has used multiple Sierra generations and several bed lengths, while newer trucks can also have MultiPro tailgates, CarbonPro beds, factory liners, side storage, and other equipment that can affect fitment. A cover listed for a Sierra 1500 is not automatically correct for every Sierra 1500.
Cover construction is another major decision. Hard folding covers provide rigid panels and a more substantial physical barrier, while soft tri-fold and roll-up covers are usually lighter, simpler, and less expensive. The best choice depends on your budget, how often you need full bed access, what you carry, and how important rigid construction is to you.
For this guide, we compared current GMC Sierra 1500-compatible options using published manufacturer, Amazon, and truck-accessory information. We considered construction, fitment, bed access, weather protection, installation, security, and everyday usability. We have not personally tested these products, so hands-on performance claims are not presented as testing results.
Fitment should always be confirmed on the exact product listing before ordering, particularly for 2019 trucks, different bed lengths, CarbonPro beds, MultiPro tailgates, and factory cargo equipment.
If you want a premium hard folding cover for a newer Sierra 1500, the BAKFlip MX4 is a rigid aluminum-panel option for applicable 2019–2026 Silverado/Sierra configurations. The Gator EFX is another hard-folding design. For a soft tri-fold, the Tyger Auto T3 is a value-oriented choice, while the Tyger Auto T1 and Gator Soft Roll Up are roll-up alternatives for applicable Sierra configurations.

Types of GMC Sierra Tonneau Covers
There is no single tonneau design that works best for every Sierra owner. Understanding the main formats makes it easier to match the cover to the way you use the truck.
Hard Folding Covers
Hard folding covers use rigid panels, commonly aluminum or composite materials. They offer more structure than a soft vinyl cover and can provide a more substantial barrier over the cargo area.
The folding format is useful because the cover can usually be opened in sections. You can access part of the bed without removing the entire assembly. The downside is that rigid panels add weight and, when folded, occupy space toward the cab.
Soft Tri-Fold Covers
Soft tri-fold covers combine flexible vinyl with a supporting frame. They are generally lighter and less expensive than hard folding covers, while still allowing the bed to be covered or opened fairly quickly.
This format can be a sensible Sierra bed cover for everyday cargo when the main objective is keeping the bed covered rather than creating a strong physical barrier against forced entry.
Soft Roll-Up Covers
Roll-up covers are designed around quick access. The flexible cover rolls toward the cab and can be secured in the open position using the supplied retention system.
This is particularly useful for Sierra owners who frequently carry tall or bulky items. With the cover rolled up, the bed remains much more open than it would with a one-piece hard shell.
Retractable Covers
Retractable covers slide into a housing near the front of the bed. They can offer a clean appearance and multiple opening positions, but the mechanism generally costs more and the housing consumes some bed space.
One-Piece Hard Covers
One-piece hard covers provide a rigid shell across the bed. They can look very finished and provide substantial coverage, but lifting the entire panel is less convenient when you need to carry tall cargo.
Which Type Should You Choose?
Your daily use should determine the cover format.
Choose a hard folding cover if you want rigid construction
If you regularly carry tools, equipment, luggage, or other valuable cargo, a hard folding cover provides a stronger physical barrier than flexible vinyl. It is also a good fit for owners who prefer the more substantial appearance of rigid panels.
Choose a soft tri-fold if value and simplicity matter
A soft tri-fold can cover everyday cargo without adding as much weight or cost as a premium hard cover. It is a practical format for drivers who do not need the additional structure of rigid panels.
Choose a soft roll-up if bed access is your priority
If you regularly switch between covered and open-bed use, a roll-up design can be convenient. It can expose most of the bed without requiring you to remove and store a rigid assembly.
Choose a retractable design if you want adjustable opening
A retractable cover can be attractive when you want a low-profile appearance and the ability to open the bed to different positions. The trade-off is generally higher cost and the front housing.
How We Chose
We evaluated the covers around the factors that matter most to Sierra owners:
- Construction: rigid aluminum or composite panels versus flexible vinyl.
- Fitment: model year, generation, bed length, tailgate, bedliner, and factory equipment.
- Bed access: how much of the cargo area remains available with the cover open.
- Weather protection: sealing, tensioning, drainage, and installation requirements.
- Installation: clamp-based and no-drill installation where applicable.
- Security: the physical difference between rigid and flexible cover construction.
- Everyday usability: opening, closing, storing, cleaning, and maintaining the cover.
Product specifications and fitment can change. Always confirm the exact Amazon variation and manufacturer fitment information before purchasing.
Detailed Reviews
1. BAKFlip MX4 — Premium Hard Folding Option
The BAKFlip MX4 is a premium hard folding tonneau cover that is sold for both Chevrolet Silverado and GMC Sierra applications. The Amazon listing reviewed for this guide is the 2019–2026 Chevy/GMC Silverado/Sierra 1500 5’10” application with MultiPro/Flex tailgate compatibility as specified by the listing. It does not fit the CarbonPro bed according to the listing.
The MX4 uses rigid aluminum panels with a matte finish. Its folding construction allows the cover to be opened in sections, giving you more flexibility than a fixed one-piece shell. Product information also lists automatic latching, perimeter sealing, and a 400-pound evenly distributed load rating for applicable versions.
That load rating should be interpreted according to the manufacturer’s conditions. It does not mean that a concentrated heavy object can safely be placed on one small section of the cover.
For a Sierra owner who wants a hard tonneau cover with a more substantial feel and flexible bed access, the MX4 is worth considering. Its disadvantages are the higher price and weight compared with soft covers, plus the space occupied by the folded panels near the cab.
Who should consider it?
- Sierra owners who want rigid aluminum-panel construction
- Drivers who regularly carry tools or equipment
- Buyers who prefer a premium low-profile appearance
- Owners who want partial bed access without removing the cover
- Buyers comfortable with premium-cover pricing
Who may want something else?
If your main goal is basic weather coverage at lower cost and weight, a soft tri-fold or roll-up design may be more practical.
Pros
- Rigid aluminum-panel construction
- Folding design allows flexible bed access
- Matte, low-profile appearance
- Stronger physical barrier than soft vinyl covers
- Automatic latching and sealing features on applicable versions
Cons
- Higher cost than soft covers
- Heavier than flexible designs
- Folded panels occupy space near the cab
- CarbonPro and other exact-fitment exclusions must be checked
2. Gator EFX — Hard Folding Sierra Bed Cover
The Gator EFX is another hard-folding option for Sierra owners who want rigid panels and a relatively clean installation. The Amazon listing reviewed for this guide is the 2019–2026 Chevy/GMC Silverado/Sierra 1500 5’10” application.
The EFX uses aluminum panels in a low-profile folding design. Product information describes sealing and drainage features intended to help manage water around the bed rails. Its folding format allows the cover to remain on the truck while you open a substantial portion of the cargo area.
The EFX can suit an owner who wants the structure of a hard cover without choosing a one-piece shell. As with other rigid covers, however, it is heavier and generally more expensive than a basic soft cover.
Who should consider it?
It is worth considering if you want hard panels, folding access, and a relatively low-profile appearance for an applicable Sierra configuration.
Pros
- Rigid aluminum-panel construction
- Low-profile hard-folding design
- Useful bed access when folded
- Perimeter sealing and drainage features
- No-drill style installation on applicable applications
Cons
- Heavier than soft covers
- Costs more than basic flexible covers
- Folded panels occupy bed space
- Exact Sierra bed and equipment fitment must be confirmed
3. Tyger Auto T3 — Soft Tri-Fold Value Option
The Tyger Auto T3 is designed for owners who want a straightforward soft tri-fold cover without the price and weight of a premium hard system. The Amazon application reviewed here is for 2019–2026 Chevy Silverado and GMC Sierra 1500 trucks with the 5’10” bed, with important configuration exclusions.
Tyger describes the T3 with dual-coated 24-ounce marine-grade vinyl, aircraft-grade aluminum frames, and stainless-steel clamps. The horizontal crossbars are pre-assembled and fold with the cover, so the bed can be opened without removing each crossbar.
Tyger specifically lists fitment limitations for the 2019 Silverado 1500 LD/Limited configuration and CarbonPro bed, as well as certain factory side-storage setups. The product information also notes potential interference with power tailgates and installation considerations for some over-the-bedrail bedliners.
These details are especially important for Sierra buyers because a generic “2019–2026 Sierra” description is not enough by itself. Match the exact product variation to the truck.
Who should consider it?
The T3 is a sensible option if your priorities are everyday coverage, simple operation, and lower cost rather than rigid security.
Pros
- 24-ounce marine-grade vinyl construction
- Aluminum frame with stainless-steel clamps
- Simple tri-fold operation
- Pre-assembled folding crossbars
- Five-year U.S. warranty listed by Tyger
Cons
- Less physical security than hard covers
- Important generation and bed-specific exclusions
- Some bedliner configurations may require modification
- Can interfere with certain power-tailgate setups
4. Tyger Auto T1 — Soft Roll-Up for Maximum Bed Access
The Tyger Auto T1 uses a soft roll-up design that prioritizes bed access. The Amazon listing reviewed for this guide is intended for 2019–2026 Chevy Silverado and GMC Sierra 1500 models with the 5’10” bed, with fitment exclusions that should be checked before purchase.
The main advantage is the opening mechanism. The cover rolls toward the cab and can be secured open, making it useful for Sierra owners who regularly carry tall or bulky items and do not want a stack of rigid panels behind the cab.
Tyger describes the T1 with dual-coated marine-grade vinyl, an aluminum side-rail/frame system, adjustable tension, and clamp-based installation. As with any Sierra tonneau, bedliners, tailgate equipment, factory rails, and other accessories can affect installation.
Who should consider it?
This cover is worth considering if quick bed access, lower weight, and a soft construction matter more to you than the stronger physical barrier provided by hard panels.
Pros
- Roll-up design provides broad bed access
- Dual-coated flexible vinyl construction
- Adjustable tensioning
- Lighter alternative to hard covers
- Five-year U.S. warranty listed by Tyger
Cons
- Less physical security than rigid covers
- Exact Sierra generation and bed length must be confirmed
- Flexible material needs appropriate care
- Rolled cover remains near the cab when open
5. Gator Soft Roll Up — Low-Profile Roll-Up Alternative
The Gator Soft Roll Up is another flexible option for Sierra owners who value straightforward operation and open-bed access. The Amazon listing reviewed here is for 2019–2026 Chevy/GMC Silverado/Sierra 1500 trucks with the 5’10” bed.
Gator describes this type of cover as a low-profile vinyl roll-up design with no-drill installation on applicable vehicles. When open, the cover rolls toward the cab rather than leaving a rigid stack across the bed.
This format can be useful for owners who use the Sierra as a working truck and frequently change what they carry. The trade-off is the same as with other soft covers: flexible vinyl does not provide the same physical barrier as rigid aluminum or hard-shell panels.
Who should consider it?
It makes sense for buyers who want a lighter roll-up cover and value bed access more than hard-cover construction.
Pros
- Soft roll-up configuration
- Low-profile appearance
- Broad bed access when rolled open
- No-drill style installation on applicable models
- Generally lighter than hard folding systems
Cons
- Less physical security than rigid covers
- Exact bed length must be confirmed
- Flexible vinyl needs regular cleaning
- Open cover remains rolled near the cab
Sierra Generations and Bed-Length Fitment
The most important part of buying a Sierra tonneau cover is matching the cover to the truck. GMC has changed Sierra body dimensions, bed rail designs, mounting points, and available bed lengths across generations.
GMT800 Sierra 1500 — roughly 1999–2006
Older Sierra 1500 trucks use different tonneau applications from newer generations. Depending on cab and configuration, these trucks were available with standard and long-bed configurations. A cover listed for a 2007–2013 Sierra should not be assumed to fit a 1999–2006 truck.
GMT900 Sierra 1500 — roughly 2007–2013
The 2007–2013 Sierra 1500 introduced another set of bed dimensions and rail configurations. Tonneau listings for this generation commonly distinguish between approximately 5’8″, 6’6″, and long-bed applications. Use the exact truck configuration rather than relying on the Sierra name alone.
K2XX Sierra 1500 — 2014–2018
The 2014–2018 Sierra 1500 has vehicle-specific tonneau applications that differ from both earlier and current-generation trucks. Common listings distinguish between approximately 5’9″ and 6’7″ beds. Factory equipment can further affect compatibility.
T1XX Sierra 1500 — 2019–2026
The current-generation Sierra 1500 uses different cover applications from the earlier truck. The 5’10” bed is a common tonneau-cover application, while 6’7″ versions are also available. Product pages can distinguish standard Sierra models from special bed configurations.
Why 2019 requires extra attention
2019 was a transition year. GMC sold the new-generation Sierra alongside the Sierra Limited, so a product that says “2019 Sierra” is not necessarily compatible with every 2019 truck. Check whether the listing specifically identifies your body style.
Measure and verify before ordering
Do not choose a cover solely from the “GMC Sierra 1500” name. Confirm the model year, body style, bed length, tailgate, bedliner, rails, and factory accessories. A correctly labeled Sierra cover can still be wrong for your particular configuration.
What to Know About a 2023 GMC Sierra 1500
The 2023 GMC Sierra 1500 belongs to the current T1XX generation, which means it uses the newer bed and rail architecture rather than the 2014–2018 design. This is important when searching for a tonneau cover because older Sierra listings can look similar in generic search results but use different mounting dimensions.
For a 2023 Sierra, the exact bed length remains critical. Current applications commonly distinguish the 5’10” short bed from the longer 6’7″ bed. The truck’s tailgate and factory equipment also matter.
2023 Sierra with MultiPro tailgate
If your 2023 Sierra has the MultiPro tailgate, choose a cover whose application explicitly supports it. Some hard folding covers are designed around this tailgate configuration, while other covers may have limitations.
2023 Sierra with CarbonPro bed
CarbonPro is a separate fitment consideration. The BAKFlip MX4 listing used in this guide specifically excludes the CarbonPro bed. Do not assume that a cover fitting a standard 5’10” Sierra bed also fits CarbonPro.
2023 Sierra bedliner considerations
Bedliners can change how mounting clamps and seals sit on the rails. Over-the-rail liners are particularly important to check because some clamp designs may require adjustments or a small opening in the liner.
If you are shopping specifically for a 2023 GMC Sierra 1500 tonneau cover, use the Amazon vehicle selector and the manufacturer’s fitment guide together. Confirm the year, bed length, tailgate, and bed construction before purchasing.
MultiPro Tailgate, CarbonPro Bed, and Factory Accessory Compatibility
MultiPro tailgate
The MultiPro tailgate is one of the most important modern Sierra fitment details. Some covers explicitly accommodate it, while others may interfere with its operation. Verify the exact listing rather than assuming all folding and roll-up covers work with the tailgate.
CarbonPro bed
CarbonPro uses a different bed construction and should be treated as its own fitment category. If the product listing excludes CarbonPro, do not order it simply because the bed length matches.
Power tailgate
Some soft tonneau covers can affect power-tailgate operation or require a particular closing sequence. Read the installation notes for the exact cover and Sierra configuration.
Bedliners
Spray-in and drop-in bedliners can affect the position of clamps and seals. Over-the-bedrail liners deserve particular attention. Follow the cover’s installation instructions rather than improvising around the liner.
Factory side storage and cargo systems
Some Sierra configurations have factory storage boxes, rail systems, or other cargo-management equipment. These components can occupy the same space needed by tonneau rails or clamps.
Bed racks and toolboxes
If you already use a bed rack, ladder rack, toolbox, or other accessory, verify compatibility before buying. Some covers are designed to work with specific rack systems, while others need unobstructed bed rails.
Weather Protection and Security
Weather resistance and security should be considered separately. A cover can do a good job of shielding cargo from rain while still providing only limited protection against someone determined to access the bed.
For everyday cargo such as groceries, luggage, sports equipment, or camping gear, a properly installed soft cover can provide useful coverage and keep the contents less visible. It is also generally lighter and easier to remove.
If you routinely leave expensive tools or equipment in the Sierra overnight, a rigid hard cover deserves more consideration. Hard panels create a stronger physical barrier than flexible vinyl, especially when the tailgate is locked.
Even a hard tonneau is not theft-proof. The tailgate, locks, hinges, and other parts of the truck remain potential access points. High-value equipment may be better protected by dedicated locking storage in addition to the cover.
No tonneau cover should be treated as completely waterproof. Water can enter at the tailgate, corners, bulkhead, seals, and drainage areas. Installation alignment is just as important as the cover design.
If cargo cannot tolerate moisture, use waterproof containers or bags inside the covered bed. The tonneau should be considered one layer of protection rather than a guarantee against every drop of water.
What to Consider Before Buying
Confirm the Sierra Generation
Identify whether your truck is GMT800, GMT900, K2XX, or T1XX-era. Do not assume that a cover designed for one generation will fit another.
Check the Exact Bed Length
Confirm the bed application shown by the manufacturer. Current Sierra listings commonly distinguish 5’10” and 6’7″ beds, while older generations use different dimensions.
Pay Special Attention to 2019
Check whether a 2019 listing is for the new-generation Sierra or the Sierra Limited/body style. The model year alone is not sufficient.
Check the Tailgate
Verify compatibility with the standard tailgate, MultiPro tailgate, power tailgate, or other factory configuration on your truck.
Check for CarbonPro
If your Sierra has a CarbonPro bed, confirm that the exact cover is designed for it. Do not rely on bed length alone.
Check the Bedliner
Review the installation notes for spray-in, drop-in, over-the-rail, or under-the-rail bedliners. The clamp system can interact differently with each type.
Decide How Much Physical Security You Need
Hard panels generally provide a stronger physical barrier than flexible vinyl. If you routinely carry valuable tools, decide whether that added structure justifies the additional cost and weight.
Think About Full Bed Access
Roll-up covers are useful when you regularly carry tall or awkward cargo. Folding covers can be convenient for normal cargo while still providing partial opening.
Consider Weight and Storage
Hard covers are generally heavier. If you expect to remove the cover completely, consider where you will store it and whether you can safely handle its weight.
Check the Warranty
Warranty terms vary between brands and products. Check what is covered, how long the coverage lasts, and whether seals, clamps, hinges, tension components, and other hardware have separate terms.
Check the Exact Amazon Variation
Amazon product families can contain multiple truck applications. Before purchasing, make sure the selected variation shows your Sierra year, bed length, and configuration. An ASIN for one application should not be assumed to fit another.
Installation and Fitment Tips
Many Sierra tonneau covers are designed for straightforward installation, but small fitment errors can cause uneven gaps, loose clamps, or water intrusion.
Read the vehicle-specific instructions first
Lay out the rails, clamps, seals, brackets, and cover before tightening anything. Compare the hardware with the instructions for your exact Sierra application.
Clean the bed rails
Dirt and debris can prevent seals and clamps from sitting correctly. Clean the mounting surfaces before installation.
Center the cover
Position the cover evenly from side to side before final tightening. Uneven positioning can create gaps and make the cover difficult to latch.
Check tailgate clearance
Open and close the tailgate carefully after installation. Confirm that the cover does not bind against the tailgate and that the MultiPro or other factory function remains usable as intended.
Inspect the front seal
The bulkhead area near the cab is an important sealing point. Make sure the front seal is positioned correctly according to the manufacturer’s instructions.
Test the cover before loading valuable cargo
Operate the cover several times after installation. Inspect clamps, latches, and seals, and consider a simple water check to identify obvious gaps before relying on the cover in heavy rain.
No-drill does not mean universal fitment
No-drill describes the installation method. It does not mean the same hardware fits every Sierra generation or bed configuration.
Soft vs. Hard Sierra Tonneau Covers
| Factor | Soft Covers | Hard Covers |
|---|---|---|
| Typical cost | Lower | Higher |
| Weight | Usually lighter | Usually heavier |
| Physical security | Basic | Generally stronger |
| Bed access | Roll-up or fold-up | Fold, flip, or retract depending on design |
| Installation | Often simple clamp-on | Often clamp-on with heavier hardware |
| Open-bed storage | Rolls or folds near the cab | Panels or housing occupy some space |
| Best suited to | Everyday coverage and lower cost | More substantial construction and security |
The choice should follow your Sierra’s actual workload. A soft cover can be practical for everyday cargo, while a hard cover can make more sense when tools and equipment regularly remain in the bed.
Maintenance and Long-Term Use
Routine tonneau maintenance is straightforward, but regular attention can help preserve the material, seals, hardware, and appearance.
Keep vinyl and panels clean
Road grime can build up around hinges, seals, clamps, and folding points. Use the cleaning products recommended by the manufacturer and avoid aggressive chemicals that could damage the finish or vinyl.
Inspect seals and drainage
If water reaches the bed, inspect the front seal, side seals, corners, tailgate area, and drainage paths. Water intrusion can result from alignment or installation as well as from the cover itself.
Check mounting hardware
Inspect clamps and other mounting hardware periodically. If something becomes loose or shifts, correct the issue before continuing to use the cover.
Follow load limits
If the manufacturer publishes a load rating, follow its conditions. Evenly distributed weight is different from placing a heavy object on a small portion of a panel.
Secure the cover before driving
Use the supplied straps, latches, supports, or other retention system when the cover is rolled or folded open. Do not drive with a partially open cover unless the manufacturer provides a secure method for that position.
FAQs
What is the best tonneau cover for GMC Sierra 1500?
There is no single cover that fits every Sierra configuration. For applicable newer 2019–2026 5’10” trucks, the BAKFlip MX4, Gator EFX, Tyger Auto T3, Tyger Auto T1, and Gator Soft Roll Up represent different combinations of hard or soft construction, folding or roll-up access, and price. Your exact truck fitment should determine the final choice.
What is the best hard tonneau cover for GMC Sierra 1500?
For applicable newer Sierra configurations, the BAKFlip MX4 and Gator EFX are two hard-folding options worth comparing. The important point is to verify the exact bed length, body style, tailgate, and CarbonPro status before ordering.
What is the best tonneau cover for GMC Sierra?
The best fit depends on the Sierra generation and bed configuration. A hard folding cover can suit owners who want rigid construction, while a soft roll-up or tri-fold can make more sense when lower weight, cost, or full bed access is more important.
What is the best tonneau cover for a 2023 GMC Sierra 1500?
For a 2023 Sierra, first confirm whether you have the 5’10” or 6’7″ bed, whether the truck has a MultiPro tailgate, and whether it has a CarbonPro bed. Once those details are confirmed, compare only covers whose product listings explicitly match them.
Will a 2019 Sierra tonneau cover fit every 2019 Sierra?
No. The 2019 model year includes different Sierra body styles. A cover for the new-generation Sierra should not automatically be assumed to fit the Sierra Limited.
Are hard tonneau covers more secure than soft covers?
Generally, rigid panels create a stronger physical barrier than flexible vinyl. However, a tonneau cover is not theft-proof, and overall cargo security also depends on the tailgate, locks, storage system, and how the cargo is secured.
Are GMC Sierra tonneau covers waterproof?
Most are designed to resist rain and road spray, but they should not automatically be considered completely waterproof. Seals, corners, the tailgate, installation alignment, and drainage all affect water intrusion.
Can I use a tonneau cover with a MultiPro tailgate?
Some covers are specifically designed for Sierra trucks with MultiPro tailgates. Others may have limitations. Check the exact product fitment notes before buying.
Can I use a tonneau cover on a CarbonPro bed?
Only if the specific cover is designed for CarbonPro. Some popular covers explicitly exclude CarbonPro, so matching the bed construction is as important as matching the bed length.
Can I use a tonneau cover with a Sierra bedliner?
Usually, but the installation depends on the liner type and cover design. Over-the-bedrail liners can require special attention around clamps and seals.
Do I need to measure my Sierra bed?
You should confirm the exact bed length and vehicle application before ordering. Different generations and cab configurations use different bed dimensions.
Can I drive with a Sierra tonneau cover rolled or folded open?
Only when the manufacturer provides a secure method for that position. Use the supplied retention straps, supports, or latches exactly as instructed.
Final Thoughts
Choosing a tonneau cover for a GMC Sierra 1500 starts with fitment. Generation, bed length, the 2019 body-style distinction, MultiPro tailgate, CarbonPro bed, bedliner, and factory accessories can all change whether a cover is suitable.
For owners considering hard folding construction, the BAKFlip MX4 and Gator EFX are two options to compare. If you want a lighter soft cover, the Tyger Auto T3 offers a tri-fold format, while the Tyger Auto T1 and Gator Soft Roll Up provide roll-up alternatives for applicable Sierra configurations.
Before purchasing any GMC Sierra bed cover, confirm the exact model year, generation, bed length, tailgate, bed construction, and factory equipment on the product listing. That final fitment check is the most important step in getting a cover that works properly with your truck.
