It's pretty rigid, as I've be moving it around on the dolly the dolly flexes but the camper doesn't and will rock back and forth on the dolly.

How I'm mounting it I'm hoping for a little flex, but I'll be watching it and carrying backup tie down straps if something gives.
I don't think there is anyway to build a camper that flexes unless the sides are fabric or the whole thing is made of rubber. The engineer who built the Super Camper designed a rear mount that pivoted in order to allow the frame to flex while travelling over rough terrain without cracking the camper.
