I was kinda paranoid about the corrugations in my truck bed. I imagined that the bottom edge of the camper would be hanging over a low spot and not be supported. When I hauled the Bigfoot back from Maryland I had a 4x8 sheet of plywood with a Tractor Supply bed mat over that. I was thinking I was good but began reading here about the Bigfoot needing support under the wings behind the fender wells. Someone here had a pic of a plywood completely covered bed, and I did that. So I'm feeling better about supporting the floor.
I wonder if those folks that are using a bed mat only are having the camper hunting for a home in those low corrugations.
I also think the spring slack in the Fast Guns could allow the camper to move a little. Roads bumps pushing against the spring tension and pulling against the compression of opposite tie downs.
I never have measured it but plan to now.
