Just got back from Promised Land State Park. Practically winter camping with highs in the 30s, 50mph winds gusts and 25 mph-sustained winds. Rain and every leaf went down. I was in my NTM off grid pup on a shake down trip. No battery power, furnace was thus non functional. Had a space heater and bed heaters going. Lots of fun regardless.
Using it again this weekend with my kids for Halloween fun. Last night, Slapped a group 31 120ah wet cell trolling motor battery from my fishing boat and tested the full furnace functionality. Over winter mod all lights to led, 6vt battery bank and install a fantastic fan in the vent.
