We have been on the road now for 75+ days. Some of the roads we have traveled have been less then smooth.(Dirt,Gravel, BLM) While in Grand Junction CO, I was filling the propane tanks at Tractor Supply. I noticed both connections on the hoses at the tanks to the regulator had developed leaks. Holy s--t batman! Luckily, T.S. had Mr. Heater replacements. Replaced and rechecked for leaks, O.K. so far so good. Our hull #104 2015, Please remember to do a leak test on your hose fittings.
