Greetings, On our last outing I noticed a dripping from the underside of the pup. The liquid was coming from where the propane line enters to the heater. We do not use our heater because it drains a tank pretty quickly. The heater, fuse box inverter and electrical storage cabinet share one large cabinet. There is a panel between all three. I looked inside the electrical cord storage area and could not see anything. I also pulled the metal screen on the inside on the heater and couldn't see anything. I haven't looked below where the inverter is yet because the camper was plugged in and I didn't want to get shocked. From what I can tell from the underside of the camper it has leaked water? before. Any ideas? We typically camp in spring and summer. This was our first cold camp in 5 years (Texas cold) It got down to 38 one night and the high was 51 during the day.
