I do mine a little different, I live in Canada it gets cold. I crib my coach in 3 spots so the frame can not twist, 2 at the back in front of the drive axel and 1 at the front weldment for the ZF suspension. moisture in the air is a problem I have had the moisture condense in the tanks and block the ports and stop air flow, I have a dental compressor in the shop with a water separation system on it, water can still freeze in the air line, you can't change the rules of physics ,I replumed my air lines so that I can supply air to the seals and door only, less places for a air leak, when it gets cold fittings can start to leak,  I have a house alarm system with a connect to go module in it  that will email me if  lose air pressure or my battery voltage goes under 12.5 . The 1st year I had my coach the breaker tripped I lost air and heat I could not open the door I thought it was frozen, just would not open from low air pressure  and i did not know how  open it. Some of my mirrors in the ceiling cracked from the cold so have some heat in the coach. Now I leave my coach at my friends house in Florida on cribs with alarm system hooked up.
