Estimated 10,000 miles as RV has only traveled several times between Virginia and Florida, after it was purchased in Ohio. Asking $45,000. Also have a 2013 Chevrolet Silverado 3500 LTZ, that I would sell along with, as a pair for $85,000. Have had vent fan replaced and roof membrane. Membrane was replace due to pin holes that were probably caused by road debris. No leakage. Please see specifications at links below. Also, RV has custom made canvas skirting made from semi-trailer canvas. This skirting keeps out cold and heat alike. www.rvguide.com/specs/dutchmen/toy-hauler/2015/voltage/3970.html www.rvguide.com/specs/dutchmen/toy-hauler/2015/voltage/3970/print.html
