OK. OP here. Maybe I posed my question wrong. I'm really not interested in whether someone would make a long distance purchase of an RV. My question is :Given the cost of used RV's it's interesting that there aren't certified RV's inspection services available that specialize in pre-sale inspections.
As to my son in laws situation, the RV sold before he had a chance to really get further into the details and while we were discussing this RV, the thought of RV surveyors came to me and I thought I would put the question out here.
