1). SKIRTED TOPPERS - Toppers that are skirted or that come down past the base rail of the box of the truck will not support the tilt-A-Topper kit.

2). STEP SIDE TRUCKS – there is no application for ANY step side trucks. (Step side trucks have no inside flange to which the brackets mount.

3). BEDLINERS – Tilt-A-Topper Kits will work with most bed liners. In some cases the bed liner will need the be cut to allow the clamping system to be installed. (We offer heating knifes for an additional cost if $25.00)

4). CHEV LUV & DATSUN -  there is no application for these trucks

5). OUT-SIDDED BOX FLANGE – most truck boxes come with the flange facing the inside of the box. This is where the clamping system connects. With boxes where the flange faces on the out side, there is no way to connect the Tilt-A-Topper Kit to the out side of the box.
