I just bought two bunk bed mattresses from a parted out camper. Due to insurance purposes, I was not allowed in the trailer, but I could stick my head in through the doors to look around. If a part is needed, the owner or a yard worker pulled that part. They advertised it on Craigslist with the rules, etc. They sold the parts as "best offer." They knew how much stuff was new and what it should go for, taking into account damage from the RV being rolled. Best $100 I had ever spent. I'd do it again if I need any other parts.
