Hard roll-up tonneau covers are a relatively new entry to the truck bed cover market, but they’ve become one of the most popular tonneau categories. This is thanks to their best-of-both-worlds design: the seamless appearance of a soft bed cover with the superior security and weather resistance of a hard bed cover. If you’re interested in a hard-rolling truck bed cover, you’ve probably run into the BAK Revolver X4 and TruXedo Sentry CT. These covers are superficially similar, but there are some key differences between the two that will help you decide which is the best tonneau cover for your truck.

Shared Features

Hard-Rolling Tonneau Cover: The cover is made of aluminum slats with a soft overlay.
Low Profile: The cover sits less than an inch above the bed, providing a sleek look that doesn’t detract from the body lines of your truck.
Water Resistant: The soft overlay sheds water off the sides of the cover.
Secure: Close the cover, lock your tailgate, and rest assured that items in your bed are secure.
Made in America: The cover is manufactured in the USA.
