Best used four season Class C MH
I'm told the following:
Chinook (Glacier or Summit may meet your needs; mine is a Class B). I know several folks that use their Chinook in all 4 seasons.
Bigfoot has among the best insulation. I looked at them when considering rigs. I have tank heaters, thermopane windows, both heat pump and furnace, and the full fiberglass design means there isn't risk of condensation forming in the walls due to heat/cold variations and delamination of the structure. 4WD was also an option.
