Chassis/Walls/Roof Twisted after Collision on Class A MH?

We were rear-ended by a loaded dump truck. It pushed the motorhome box of our class C forward hard enough to dent the truck cab before rebounding. The water lines were pulled out of the pump so water everywhere. Minimal damage inside and we could still drive it but the roof had a distinct ripple and the frame was definitely twisted.

Fortunately we had replacement coverage so our insurance company paid out and sold our motorhome to a salvage company. Good luck - let us know how it goes.
