Burning man,
I have to disagree with your assessment because you used a static model. In motion, hard braking does transfer weight to the front and the resultant compression of the front suspension. How do I know this? A few times when installing the camper on the truck, I missed getting it all the way to the front rubber bumpers/snubbers. I only needed 2 or 3 inches forward and had already removed my jax. So, what to do? I sped up down the lane to about 10 mph, making sure i was on the flat and slammed on the brakes. What happened? Two things: The camper slid forward with the rear edge lifting slightly, even on that sticky, thin mat. The overhead sleeping part dipped about 4". The front suspension of the truck compressed and dropped down also then rebounded. Job done. I noticed over the years that the wear on the bottom side edges of the floor was getting beat up, much of it by the Lance Camper Guides. I installed 2x2 aluminum "L" strips along the exterior sides of the floor of the box and I'm thinking these made the slide easier and acted as mini skids. jefe
