We camped in our Rockwood 8329SS (twin to Flagstaff 832IKBS) over the weekend, and Friday night it got down to 21 degrees. I left the vanity in the bath open at night to give some warmth to the pump, backside to the outside shower and water connections.
We ran a space heater in the bedroom set on 65 degrees, and set the furnace for 60. Also ran the tank heaters, and I only heard the furnace run a couple of times.
An extra blanket on the bed kept us comfy, and no plumbing issues at all.
I took out the hinge on the left side of my vanity door, and installed a regular latch.
This makes getting to the pump bypass much quicker, not sure why FR wants to screw these doors shut since you need in there to winterize.
