As far as Pre-purchase Inspections, I would certainly research inspection services independent of any dealer. Sorry, I just do not trust dealers. They are there to sell to make a living. Too often at the expense of truth. There is qualified/certified RV inspector sin various parts of the country, but not in every location. Prices range from $500 to $1,500. This process is not unlike buying a house, it is money well spent, if, you go into it ready to walk away from what seems like a good deal. I firmly believe, when buying an older used coach, the selling price is just the beginning. If you plan for the additional expense up front, there will not be as many disappointments.
