That is a nice Airstream. The photos were taken on the property of P & S Trailer Service on old US 6 just west of the small town of Helena, OH. P & S has a website. Do a google search under P&S Trailer. I'll look it up and post it after I send this post. Steve Ruth and his son Kevin have been replacing body panels, restoring Airstreams, and doing recoating or polishing of Airstreams for many years. They are recommended by the Airstream factory at Jackson Center, OH. That is the way I met them. I pulled my 34' A/S all the way from Lubbock to Helena, OH to have them work on it.
It is not clear but the trailer probably belongs to Steve Ruth. He buys, repairs, and resells a few. Steve does high quality work and stands behind his work. I know him personally. He recoated a '93 Airstream Excella 34' for me in 1995 or '96 and recently polished my daughter's vintage '66 Airstream Safari 22' (gift from her dad).
My guess is the former owner was probably elderly, as many Airstream owners are, and probably was not a skilled trailer puller. It sounds like he dinged each of the four corner panels which is fairly common. It is also easy because of the long rear overhang to hook and damage the rear bumper. Steve Ruth probably replaced the four corner panels and the rear bumper.
If you are serious about the trailer call and talk to Steve Ruth about it. He is honest.
