Frame Stiffing to reduce Porpoising?

I had the same rig for a little while and here's what I found out.

The bed opening width is minimal. The curved part at the bottom necessitated that I use two pieces of plywood to raise it above the curvature.

Make sure your bed is flat. On my new GMC truck the bed is crowned front to back, which necessitated different pieces of plywood of varying thickness.

Re the center of gravity. I had race car scales so I put my camper on them. If you look at some of my old posts you can find out what I found out. There guesstimate is best case, what I found out was different. Though the cog was behind the wheels a bit, I didn't find it to effect the driving.

Also on my F250 I had the biggest spring pack installed and largest sway bar. I still didn't like the way it drove. The cog is just so high.

I removed and reinstalled my jacks on the camper. When they installed them the holes in the brackets were too small for the fasteners used there is no way they would pull up tight against the camper. So I enlarged the holes in the brackets and reinstalled.

Also if you have a gooseneck ball in the bed, you can install the plywood on the bed with a hole that matches this and install a stub into and flush with the plywood to hold it in place, or two pieces if that is what you do.

Good luck.
