Flagstaff 831FKBSS- no heat
I also am on the road with no working heater. ours is new this year, swapped all but the motor-furnace unit and did not solve. have no worthwhile recommendations, posted my symptoms and had it looked at by RV repair guy, no joy. hope your weather supports you.
our area heaters are helping but not as good as desired. area temperatures at night are 45 to 50 and forecast is good to get us home.
