Did de-winterize mine a week before Easter and used it for 8 days during Easter and a few nights it was 25F. It has an enclosed underbelly but I have camped in that temperature without a enclosed underbelly. I moved the low drain valves inside as they where under the TT before.
Lucky we could have a fire as there's now a fire ban. We had a full house 5 adults, one baby and 5 small dogs and one big one. But it was fun. So now I'm still remodeling and fixing odds and ends. Planning to use it during this winter in Alberta so probably have to make skirting before fall.
