This happened to a friend of mine who elected to repair it himself.
He was quite proud of his repair to a seemingly minor left rear accident.
Unfortunately, to his horror, he discovered after his first winter that the right front was delaminating due to hidden damage from the "racking" of the frame and structure at impact.
Once hit (IMO), it is time to repair and sell as soon as possible. You might regret keeping it until it is too late to trade due to "fatal" hidden damage.
While he did not get a photo of the camper shedding insulation and clothing down the highway as the wall peeled away, here is a photo of his "repair" of the front so he could get it home.
It is now a near total loss and sold as a hunting cabin for 1400 bucks. (Sorry called Sam and I had the amount wrong)
