It is definitely possible to travel and use your Bounder in February, but be prepared.
We have a 2014 Southwind and travel from Ontario to Florida each January, spending 2-3 days in zero to sub zero temps.
On our coach:
1) the forced air propane furnace "is" ducted into the basement area keeping the fresh, black and grey tanks from freezing, just be certain the RV park's dump facilities are available in the winter
2) you will probably need to refill the propane tank every 2-3 days as the furnace will be running 24/7 and the heat pump will not work in cold temps
3) we supplement the coach heating with a small space heater when connected to shore power
4) can't speak to the actual snow load limit, but a 250 pound man can walk on the roof with no issue so wouldn't think you should have a problem. If necessary, get up on the roof and clear it.
5) your fresh water hose will freeze unless if you use the "heated" type hose
6) we watch the weather and will not travel on snow days and icy roads as these RV's are not like handling a car in winter
7) try to secure a parking spot that has some wind protection
8) purchase 2 remote thermometers @ ($14.00 Walmart) place 1 sensor in the wet bay and 1 in the utility bay and monitor the temps from inside the coach. In -4F temps last January, ours never went below 36F
All the best with your adventure.
