Gossman: All old RV's, especially motorhomes are money pits. You have already got the poor owner down to half the price she wanted. You are not going to get a new rig for a few thousand dollars. Yes, tires, windshields, hot water heaters, refrigerators, furnaces, brakes, electrical and suspension issues all cost money. Eventually the engine and transmission will need work. Figure a couple of thousand dollars a year, depending on who does the repair. Then there is insurance, license fees, and the cost of gas at 8 to 10 mpg.
