what was done is to lay a 2x4 or other piece of wood on the sides to meet the

was laid on that..  worked fine.  the factory bed wasnt used.
Chris,

Even with a half inch thick plywood, it will be hitting up against the curved
fiberglass roof. At least that was my experience. The 2 X4 caused clearance
problems caused problems at the lower sides. Cutting them to fit caused
problems with the plywood being too high in the middle.
