Turn on your AquaHot and set you diesel generator to autostart at about 12.2 volts if your boondocking. Try to keep the snow off your solar panel(s) too. Don't forget to turn on the AquaHot engine heat before you plan to startup to leave.
Every winter we take our MH to the mountains of CO and/or NM and stay in it. We don't boondock for long when staying in it in the winter in the mountains. We take additional electric heaters with us. One is a large oil filled radiator type, and the other is a small ceramic cube.
Last winter we took or 98 42' Signature to Leadville and stayed at the RV Coral for more than a week. On new years eve temps dropped to minus 20. That coach was equipped with a AquaHot system. We plugged into the parks 50 amp service. We don't have a heated fresh water hose or heated sewer hose so we used our onboard fresh water and sewer tanks. The park has shower and washer dryer facilitys. At nite the AquaHot diesel burner would run about a third of the time, but during the day the AH electric heat element did most the work. The radiant heat from the AH kept the basement lines and tanks above freezing. We had 2 water lines freeze up. The Norcold icemaker line, and the ones running to the rear bathroom sink, and they didn't break, I guess because they're plastic. I ran the block heater on New Years just to play it safe.
The previous 2 winters we took our 98 DutchStar on ski trips without any problems. It only had a propane furnace for the living quarters, and we put the oil filled radiator that I previously mentioned in the basement. I plugged in the block heater a few hrs before it was time to startup to leave.
We are headed back to Leadville to ski again this winter, this time in our 00 Signature 43' Caesar.
We hope this helps?
