Rough Country Hard Tri-Fold vs UnderCover Flex — frequently asked
Rough Country Hard Tri-Fold or UnderCover Flex — which should I buy?
Buy the Rough Country Hard Tri-Fold if its balance suits how you use the bed, and it is the cheaper of the two. Buy the UnderCover Flex if you care most about security and bed access. Both are the same type of cover, so the decision is about execution rather than category.
Is the Rough Country Hard Tri-Fold more secure than the UnderCover Flex?
On our rating the Rough Country Hard Tri-Fold scores Medium for security and the UnderCover Flex scores High. Treat that as resistance to an opportunist rather than as a safe — no tonneau cover stops someone determined with tools and time.
Will either of these fit my truck?
Both are sold per truck and bed length rather than as one universal part, so the answer depends on your year, model and bed. Most full-size & mid-size beds — confirm your year and bed length. Check your exact fitment before ordering either.
Do either need drilling to install?
Rough Country Hard Tri-Fold: Clamp-on, no drilling. UnderCover Flex: Clamp-on, no drilling. Mainstream covers clamp to the bed rails and need no drilling, which keeps them removable and the truck's finish intact.
