BAKFlip F1 vs UnderCover Classic — frequently asked
BAKFlip F1 or UnderCover Classic — which should I buy?
Buy the BAKFlip F1 if you care most about bed access. Buy the UnderCover Classic if its balance suits you better, and it is the cheaper of the two. They are different cover types, so decide the type first — that choice matters more than the badge.
Is the BAKFlip F1 more secure than the UnderCover Classic?
On our rating the BAKFlip F1 scores High for security and the UnderCover Classic 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?
BAKFlip F1: Clamp-on, no drilling. UnderCover Classic: 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.
