That damage sure didn't look to be enough to give it a salvage title to me
I buy salvage vehicles to repair & resell and I've seen less damage than that get a salvage title.
You have to remember, the vehicle doesn't know what kind of title it has.
The current 5'ver we're using has a salvage title and the only thing we did to it was clean it and change the fresh water pump. It was supposed to have had "water damage". Five years later and I've still haven't been able to find it.
The ones with the obvious damage are the best ones to buy (such as the one linked to).
You know exactly why it was totaled.
That one looks to have a bit of flooring damage too, I can see some insulation hanging.
