MOSTPLUS 5.8FT Tri-Fold Hard Tonneau Cover vs UnderCover Flex Hard Folding Tonneau Cover

The UnderCover Flex is the stronger cover: a 3-year limited warranty, a 400 lb load rating, a gloss-black finish, and full bed access with prop rods. The MOSTPLUS is a basic tri-fold with a 1-year warranty and no published load rating, but it fits the 5'8" bed and installs with clamps and no drilling. Buy the UnderCover Flex if you want a long-lasting cover you can stand on and open fully. Buy the MOSTPLUS if you want a simple hard cover for light duty.

• Choose the MOSTPLUS if you want a no-drill hard tri-fold for the 5'8" Silverado or Sierra bed and mainly haul light, dry cargo.
• Choose the UnderCover Flex if you want a longer warranty, a 400 lb load rating, and full bed access from prop rods.
