Thanks for your comments so far. I don't know if we have a photo of the damage here at the house. I will check with my husband. I think the damage was membrane only.
Trading in/up is not because of the damage. It's because we quickly figured out that our trailer would not meet our needs for very long and we now have a bigger truck. Financially, this is a good time for us to make the move.
If we were keeping this trailer, we would just do the repair and keep on camping.
But we do not intend to keep it. I guess the question is, is there a market for repaired trailers? There must be. Another issue is that we do not have road frontage to put a camper out for sale.
