Sweeney, how did your plumbing hold up in 21 degree weather? I've only been to about 30 which was obviously no problem. I just booked the last two weeks of September where temps are supposed to "average" 32 for a low. Of course that's the whole month so the last half should be colder than the first half. But of course they could get a lot colder. I can handle the temps fine but I really want to have a functioning galley the whole time. Don't want to have to winterize mid trip.
Thanks.
Good question. Yes, This is probably not a major issue for us, as we don't normally camp that cold. Not because of night cold but day ... days in the 50's nights in the 30's is about where we start camping.
To be honest, the only regret I have with our rig is the furnace. In retrospect, I doubt we'll use it enough. 99% of the time we will be in a place with electricity --- this may change (hip camp type places) when I can't get into a state park, or all I can get is a non-electric. But those times are rare. A 400 watt personal heater warmed the cabin WELL above my comfort point in just a few minutes...I had to turn it off, and/or regulate it by opening windows.
As for the freezing, the tanks are freeze safe, so thee's no problem there. The most "damageable" part in a freeze is the spray head and valve in the sink. As long as those are drained, I should be fine.
To drain them, turn off the power to the water pump, open the sink valve and let the preasure release. Then raise the spray valve straight up and press the button --- the water will rush out through the sink. For an added bonus, open and close the outside shower connector and you're OK for a little bit of cold.
I am really lucky though, we discovered this winter that our garage never drops below freezing ---40's at as low as it gets...so no more winterization
