As to the OP original question, nearly all states have lemon laws covering the CHASSIS portion of the motorhome for safety related defects. The HOUSE portions are specifically excluded. I believe California and Rhode Island are the only states to fully cover the entire unit. When a coach is determined to be a lemon it is repurchased by the manufacturer from the owner LESS a stipulated amount for mileage. The title is then branded as a lemon law buy back. At that point the manufacturer either sells it as-is or sends it to a auction in a friendly state such as Missouri that does not recognize out of state branded titles. In any event the coach is sold on to the next owner either with a branded or a "washed" title. Something you have to realize, the RV Industry has lobbied hard and long to keep themselves exempt from regulation. Dealing with an RV dealer or manufacturer is like the automobile business was in the 1950's or 1960's. It's pay your money and take your chances....
