Outer Wall Damage?

Hey there! We're new to these forums, but we know there's great help here. We have a 1995 Coachmen Leprechaun 29ft Motorhome. We initially had no idea of the horrors of delamination, or even the slightest clue of it's existence. Anyways, it would appear that the driver-side wall on the over cab (it's a Class C) has been ripped off. Now we know a bit more about delamination, haha. We have our insurance looking into the matter to hopefully either fix it, or to total the RV out, since it's as old as it is, and most likely won't hold enough value. We were wondering if anyone else has had their RV totaled, so we can get an idea on how common this is, or if not, how much do you think it could cost to fix it?
