I didn't move my slide in zero temps even with the vacuum pump install. Make sure the heaters in the water bay and aquahot bay work as well as the aquahot itself. The biggest problem I encountered was moisture in my air supply froze and my air doors and toilet didn't work. The humidity in Louisiana contributed to my situation. I later learned that I had eight air tanks instead of the three I could see. Heating R1 or L1, whichever gives access to your 110v compressor will help. Keep some air brake airline antifreeze in stock and you can pour it in the hose coming off your engine compressor if it freezes up.
