So first real winter camping in our Forester and thought I would share observations. En-route to Quartzsite and had a few days camping in the snow and cold. Was still winterized but wanted to see how warm the camper and water bays would stay. Temps got down to 2 but were mostly in the low teens. With the furnace set at 65 it ran allot. Exterior walls were very cold and windows had a layer of ice on the inside in the morning. Camper stayed in the low to mid 50s.
The water pump bay got down to 21 and was regularly below 32. With the furnace running I could feel warm air blowing in. Just seems like it didn’t hold any heat and quickly returned below 32 when the furnace shut off.
The sewer bay seemed a little warmer, still in the 20’s, which is odd since there is no obvious source of heat other that the arctic pads on the bottom of the black & grey tanks. They were on the whole time.
I did notice the water pump bay could be made smaller and just warm the area behind the metal door. So I stuffed towels and newspaper along the top which should reduce the size of the heated part. Whenever I get home again will probably add some insulation to the bay to seal the area better and create a smaller warm area just around the pump.
May also consider some type heat tape to warm the area before next winter camping trip.
BTW, DW not too keen about winter camping and says we need to spend the winter in Florida!
Appreciate hearing your thoughts, experience and solutions.
Thanks!
