Major repair costs for a Class C

Old motorhomes are often "money pits". The engine, transmission, and engine cooling system may be decent but often the cooling system and brakes need serious work. The dash AC is also a comfort for driver and passenger on hot days, the dash AC in an old rig is often not working. You must have safe tires and brakes or risk breakdowns on the road, possible loss of control, and serious injury/liability. The house batteries, converter charger, and starting batteries, 110volt AC power systems and propane supply must work together and will often need repairs/replacement in an old rig. Your fridge, furnace, microwave oven, and interior lights, all depend the converter charger, house batteries and engine alternator to keep batteries charged. If you have an RV generator, it can be used in a limited way to provide 110volt AC power when you are not connected to camp/shore power. Old rigs often need expensive RV generator overhaul. You need to know what items will need repair or replacement and get independent estimates for time and materials.
