How about this reasonably close estimate. Bought new gas Tropical (2000 model year) in May 1999 for $86000.00 including tax and license. Financed $60000.00. Still have the RV and still travel about six months a year. We have driven the RV 132000 miles and driven toads another 180000 miles. We fulltimed in Rv for 8+ years. I figure the whloe adventure has cost about $250000.00. Once in a while I wonder how many cruises could we have taken for that amount??? Hmmm. By the way - nothing but routine service except for a furnace, a water heater and a refrigerator. Never a breakdown while travelling. Never visited a service facility except for a scheduled item. Did virtually all maintenance myself.
