Congratulations on the new TT. They are a lot of fun.
We will sometimes go south in the winter to get a weather break. Being in Maine you would have to go way south.
However, we have winter camped at the local State Park when they had a February snowshoe hike.
We dry camped and used the heated wash house. They plowed a dozen spot but we were the only ones there. We used a ceramic space heater rather than the LP.
Most TTs are not really designed for winter use. But for a sunny weekend in February it worked out okay.
