motor home mpg

This is all true. However, many times the previous owners of an older motor home have already repaired and replaced a lot of the appliances and accessories, especially good if they have receipts for the work. Also, there may be new tires, brakes, and other assorted consumables on the unit that one purchases. So, there may not be a necessity to incur high costs for these items going forward. The thing that I would worry about, with an older unit, is the engine, transmission, and drive trane. Possibly the optimum idea would be to purchase a used motor home, that is not only in the best shape possible, but that falls within the maximum years allowed by a service contract. I think it is mostly 12 years but some are 15 years. At least that would protect against engine, transmission, and drive trane failure. The only other option, for me, is to purchase a new or late model used MH that still has the warranty and where the components are still in good shape. I can afford payments over a 12 to 15 year period and my credit score is over 800. If one is going to an RV dealer to purchase a MH what is the rule of thumb on pricing? I have heard that you should offer 30% under the listed price to start with. Any ideas if this is correct?
