The cost to maintain a camper also depends on which options you get. We did not want to maintain a water system or refrigeration system so we deleted both from our Granby. Our Granby is low maintenance with only a stove, furnace, and lights ($20-30 per year in propane, $500 in batteries after 5-7 years, $10 for 303 UV treatment per 5 years) but we have a building to store our camper inside which saves the camper in our wet/cold climate (7 inches of rain in April, 10 inches of rain in June 2013). Operating costs for camping are much larger for us: $50 per day going West, $60 per day going East for gasoline and campground fees. We are expecting major maintenance at 10 years of several thousand dollars but we camp over 100 days per year so major maintenance will average $3 per camping day. An older heavily optioned camper would have much higher costs than a new shell model. Accidental damage can add $100's each year (tires+repairs) if you are in rough country but then your operating cost, campground fees, would be much lower.
