As we were bringing my new-to-me Aliner home to Massachusetts from California, we were rear-ended in a chain reaction crash while crossing the Mississippi River approaching Memphis. The truck that hit us hit the spare tire, which probably 'spared' us more damage. The outside bumper, which holds the support for the spare, got bent in. The spare support punched a hole in the shell of the Aliner. We are so fortunate that the damage seems pretty minor. It barely impacted the inside storage, and did not affect the bed at all. Any suggestions for getting the bumper straightened? How about patching the shell? I'm attaching a few pictures.
