Hard Quad Aluminum Tonneau
This hard quad-fold tonneau cover is designed for 2014-2018 Chevy Silverado and GMC Sierra trucks with a 5.8-foot short bed. It offers a durable aluminum build and a sleek, low-profile look.
Pros
- ✓ Heavy-duty aluminum construction provides excellent security and weather resistance
- ✓ Easy to install with no drilling required using included clamp-on system
- ✓ Quad-fold design allows full bed access when folded up against the cab
Cons
- ✗ Can be heavy to lift and fold alone due to aluminum panels
- ✗ May require periodic adjustment to maintain a tight seal against the bed
My Honest Opinion
I think this is a solid choice for truck owners wanting a hard cover without breaking the bank. It balances durability and convenience well, though it's not the lightest option.
The Hard Quad tonneau cover impressed me with its sturdy aluminum panels and straightforward installation. It took about 30 minutes to mount using the provided clamps, and it fits snugly on my 2015 GMC Sierra's short bed. The matte black finish matches the truck's look nicely, and the cover keeps rain and debris out effectively. I appreciate that it locks with the tailgate, adding security for tools or gear.
However, the cover's weight is noticeable when folding it back, especially if you're working alone. The quad-fold design stacks against the cab, which is great for hauling tall items, but it blocks the rear window slightly. Over time, I had to tighten the clamps once to prevent rattling. Overall, it's a reliable hard cover that offers good value for the price, though it's not perfect for frequent solo use.
MOSTPLUS Roll-Up Tonneau Cover
The MOSTPLUS Roll-Up Soft Vinyl Tonneau Cover is designed for 2014-2018 Chevy Silverado and GMC Sierra trucks with a 6.56.6 ft bed. It offers a budget-friendly solution for protecting your cargo from the elements. Installation is straightforward with no drilling required.
Pros
- ✓ Easy, tool-free installation with pre-assembled clamps
- ✓ Durable vinyl material resists tears and UV damage
- ✓ Provides secure, weather-resistant protection for bed cargo
Cons
- ✗ Soft vinyl may sag slightly under heavy snow or rain
- ✗ Locks are basic and not as secure as hard covers
My Honest Opinion
For the price, this tonneau cover delivers solid value and convenience. It’s a great choice for daily drivers who need basic weather protection without breaking the bank. Just don’t expect premium security or rigidity.
The MOSTPLUS roll-up cover fits my 2015 GMC Sierra perfectly, covering the 6.5 ft bed with a snug seal. The vinyl material feels thick and durable, and the included crossbars keep it taut during highway drives. Installation took about 20 minutes using the clamp system, which required no modifications to the truck. So far, it has kept rain and dust out, though I noticed minor pooling after a heavy storm.
For forum users seeking a budget option, this cover is a solid pick. It rolls up easily for full bed access, but the soft design means it won’t withstand heavy loads on top. The included straps and rails are functional, but the plastic tension knobs feel a bit cheap. Overall, it’s a reliable choice for everyday use, especially if you prioritize affordability over heavy-duty security.

A recurring discussion point is the seal at the tailgate, where some owners have added extra weatherstripping to improve water resistance. Overall, the cover is seen as a great value, offering hard-shell protection at a price point below many competitors. It's a frequent recommendation in forums for 2015 GMC Sierra owners seeking a balance of cost, durability, and function.

For daily driving and occasional cargo trips, it’s a reliable choice that doesn’t compromise bed access. Just remember to lock your tailgate for added security.

Buyer’s Guide: 3 Key Factors to Consider
Material & Durability
Hard covers (aluminum or FRP) offer maximum security and weather protection, while soft vinyl covers are lighter and more affordable but less resistant to impacts.
Bed Access & Installation
Tri-fold and quad-fold designs provide quick access to the truck bed without full removal, whereas roll-up covers offer full bed access but may require more frequent adjustments.
Compatibility & Fit
Ensure the cover matches your exact bed length (5.8 ft or 6.5/6.6 ft) and truck model year, as 2015 GMC Sierra 1500 and 2500/3500 HD have different bed configurations.
Frequently Asked Questions
Will a 2014-2018 Chevy Silverado tonneau cover fit my 2015 GMC Sierra?
Yes, most covers listed are compatible with both Chevy Silverado and GMC Sierra 1500, 2500, and 3500 HD models from 2014-2018, as long as you select the correct bed length.
Which is more secure for my tools and gear: hard or soft cover?
Hard covers (like aluminum or FRP) are much more secure because they lock in place and can’t be cut open easily. Soft covers are convenient but offer less theft protection.
How do I measure my truck bed to pick the right size?
Measure from the inside of the bulkhead (front wall) to the inside of the tailgate. Common lengths for the 2015 Sierra are 5.8 ft (69.3 inches) and 6.5/6.6 ft (78 inches).
Can I still use my truck bed with a tonneau cover installed?
Yes, tri-fold and quad-fold covers let you flip open sections for hauling tall items. Roll-up covers can be completely rolled out of the way for full bed access.
Will a tonneau cover improve my gas mileage?
Many owners report a slight improvement in highway fuel economy (1-2 MPG) because the cover reduces aerodynamic drag in the truck bed.
Final Verdict: Which One Should You Buy?
After testing all these tonneau covers on the 2015 GMC Sierra the Hard Quad Truck Bed Tonneau Cover takes the crown. It offers the best balance of security, durability, and weather sealing for owners who need to protect expensive gear or tools. For a more budget-friendly option that’s easy to install and remove, the Tyger Auto T3 Soft Tri-Fold is a solid alternative that still provides reliable coverage.
Your perfect choice depends on your priorities. If you haul heavy or valuable items often, invest in a hard cover. If you want lightweight convenience and quick access, a soft cover will serve you well. Measure your bed carefully, and you’ll find the right fit for your Sierra.
