April 2012 we paid $25K for our 2004 Trail-Lite 213 with 8,200 miles on the odometer. THEN I put on 7 new tires, 2 new AGM 6 Volt house batteries, had the Onan generator serviced (new fuel lines, fuel pump and carb), new belts, hoses, added electric water heater element, added exhaust fan in living area, power management system and a new TV. 2nd trip out, last summer, we dropped the in-tank fuel pump ($800). $18-20K sounds more like for one that age to me after our experience so far. We are 6091 miles into the Alaska we bought it for, no problems, the 6.0 Chevrolet is averaging 11.08 MPG.
