As of now, some compatibility concerns are:

1. Some tool boxes, 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 complain 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''.
