Learning how to DIY is the best and cheapest route. First thing to do is go online and find manuals or instructions for everything you can and store it all in a file on your computer. Water heater, A'cond, furnace, frig, TV, microwave, cooktop, TV antenna, radio, slide system, chassis, engine, tires, water pump, awning, steps and more. Start with Thor and get manual on your coach. It will be pretty generic but it is a good place to start.
