Moving 5th wheel in below zero weather

Nothing is frozen. The site we are at has their ground water heat taped, we have our hose heat taped and inverted the water hookup. Our water hookup for the 5th wheel was outside of a storage area we have and we inverted it and drilled a hole so the hose could come up inside the storage area. We insulated the hole where the hose would normally be hooked up. We custom build OSB skirting backed with 2" hard foam insulation and then put the itchy insulation underneath where the bottom of the 5th wheel meets the skirting so no air enters underneath. We have 3 heaters running at all time under the 5th wheel. Two radiant heaters and 1 blowing heater. We also put 2" blue hard foam insulation around the bedroom slide out and window and on the sides of the living room. The main face of the living room is open and we put up insulation on the inside when it's in the teens and twenties below zero. We also have a small space heater we put under the kitchen wrap around where the water heater pump is when it's teens and twenties below. Nothing freezes! We saw -30 with wind chills at -49 a little over a week ago. Underneath dropped to low teens and inside maintained 67 degrees with one heater and the furnace on 65. Just for another perspective, we are at 16 degrees, wind at 12MPH with wind chill temp at -1. Underneath temp is at 44. Inside, no furnace running and one small heater, we are at 70 degrees. The biggest thing is to be able to make sure your skirting is perfect! No air gaps! Thank goodness for us my husband was formerly a carpenter and was able to build our skirting to perfect spec in one afternoon. Afterwards, I painted the OSB in Seahawks lime green and royal blue. You will want to paint your OSB to keep the water from soaking into it.
