Also, tested the propane system. Some time ago I replaced the thermostat with a digital one and got the fan to blow, as I had batteries hooked up, but couldn't test the heat as I didn't have propane. So, I also turned on the stove (I read in the past it was the quickest way to make sure propane was flowing through the lines) and ran the heater to make sure it was working. Everything a-okay. Remaining list: Fix the leak, check/replace the bearings, check/replace the tires, and use (only with water) the cassette toilet so I can familiarize myself with filling, using, and emptying it.
