Which type of tonneau cover?
Vinyl that rolls up toward the cab. The cheapest way to cover the bed and the quickest to open fully.
Vinyl over an aluminum frame that folds in three sections toward the cab.
Rigid aluminum or composite panels. More security and weather resistance than vinyl, at a higher price.
Slats that roll into a canister at the front of the bed.
