Our custom true flatbed truck camper build thread

Interesting project, keep the pics coming.

Re: the frame twist, a few years ago I was working on a military vehicle project and on those with boxes on the back, ie, "campers" they used a special 3 point pivoting mount system that isolated the box from the frame. It was designed such that a moment could not be transmitted from the frame to the box.

Do some searches and I'm sure you can find some info/pics of similar mounts.
