Assuming the RV is stored right now, is it protected from rain? Tweaked structure will likely cause it to be prone to leaks. If there is an expectation of it being rebuilt, I would have a big concern about water damage while it is being stored. You may get an estimate for the repairs, but by the time one gets around to fixing it, there will likely be new damage unless it is covered up.
And on that note, that would be my biggest concern with a repair. Rivets that are used to hold stuff together get stretched and no longer keep things tight. RV structure is designed to be put together once and never be taken apart. This makes it impossible to asses interior structure, and prove it is still OK.
