As of now, some compatibilities cases we have heard are:

1. Camper shells & Tonneau covers will affect the installation of this unit;

2. Bed rail top made of fiberglass instead of metal for some rare truck models like F-150 super-cab, customers complaint it not sturdy for heavy-duty purpose after making holes;

3. There are track system installed on the inner bed-wall like the New Toyota Models which blocked our mounting plates;

4. Bed width is too small for the minimum extension of 51.5".

The products is weight-tested as shown in the pictures.
