Instead of taking a motor home to a general scrap yard, try taking it to an RV company first; these companies will often purchase them for salvage or for use. These types of RV companies have locations across the United States.
RV companies often break down motor homes for salvage and sell the parts to other companies. An RV company may also purchase a used motor home to fix it and sell it to future buyers. Companies of this type include Agency RV Sales and Service in Iowa and Bob's Used RV Parts in Florida. Other companies include Colaw RV Salvage in Missouri and Economy Used RV Parts in Arizona.
