Never thought about a higher air pressure, but it sounds reasonable as long as there is faucet open so there is no build up of pressure in the lines. The air pressure is just traveling through the lines with no pressure build up. Think I might try it out.

If you really only get an occasional freezing night (as I read it), then you might consider just running your furnace when that occurs. Ditto the HW heater as long as you are sure its full. Leave the inside cabinet doors open to be sure the heat gets to the pipes.
If you have a wireless indoor/outdoor thermometer you can use the sensor to monitor the temperature in the dump and/or fresh water bays (use the max/min readings). This will give you the necessary data to determine when it is getting just TOO cold.
Also, no matter what, turn off the water pump and leave a faucet open (one ABOVE the hot water heater if it is running) so that there is no pressure in the system. Sometimes-NOT a promise-this can allow things to freeze without damaging the pipes. This just might give you a little wiggle room if you guess wrong about the temperature or run out of propane during the night or...some other darn thing goes wrong. If the system is under pressure when it freezes, the pipes are almost guaranteed to split.

The 100 psi is at the compressor----not in the lines. In fact, the regulator pressure drops to 80 psi as soon as the air starts flowing. I doubt there is even 45 actual psi in the lines--------as long as one faucet or more is open. But if start with 45 psi at the compressor, you'll be lucky to have 20 psi in the lines and you won't have enough flow to get all the water out. At least that's what I learned. I dread to think what I would have had in the spring if I hadn't up the pressure. A lot more water came out when I did.

I live in East Texas and my coach is parked beside my house and plugged into electricity. I don't winterize because I use my coach year round. If there is going to be subfreezing weather I set my furnace for 50 degrees and turn the electric water heater on if it is going to be freezing for more than a few hours. I've been doing this for 9 years with no problems.

Increasing the volumne of air sent through the lines will do more good then increasing the pressure. A small demand style air compressor will not work as well as as tank style.

It was 29o out last night when I went to bed. It was 26o when I got up and it is 30o right now as I type this. I just checked on some gallon jugs of water that are sitting on my deck. They have ice in them but they are not frozen solid. If you keep your system under pressure and you do warm up during the day I seriously doubt you would suffer any freeze damage. In the fall, I have let my rig sit many times where temps dropped into the high 20's at night and 40's during the day with out any problems at all.

I lived in Colorado for 20 years and that is all I did was blow the water lines, drain the HW heater and pour some pink stuff in the drains. Went through many winters with -20 and never had a problem.

I usuallly blow out the lines and drain the water heater and put some pink stuff in the drain traps, if it is gonna be a couple of weeks before heading out again if it is gonna be in the 20's at nites. Takes me all of about 1/2 an hour and I use maybe a gal. of pink stuff for the whole year. But if I know we will be going out in a couple of days I just turn the furnace up to 50 or so. No 20 degree nites in the forecast I don't do nothing. You probably get more 20 degree nites in West Texas then we do in Central.
