Open the low point drains and the faucets. Pour pink antifreeze into all of the traps, and hope. If you can get to the storage lot, a 12v air compressor will blow the lines. Open the faucets, plug the air compressor into your cigarette lighter, and let 'er rip.
Have you done this with a little cig lighter air compressor?
Gonna say not near enough volume output. It'll blow out a candle. It won't blow out pipes.
To the OP, 40s during the day and one mid night of mid 20s for a few hours won't freeze the pipes.
The problems arise when 1 night turns into 2 or 5 and the camper is stored in the shade, and it's not really just 4 hours becasue there's a temperature inversion in the morning and it really was 20 deg down in the holler when the official forecast was 26 and you don't have the time, so you don't bother, and, and, and.......
Most "woe is me"stories don't tell the whole story......I.E. One. Doesn't want to admit they screwed up on the World Wide Web, so "It only got down to freezing for 6 hours, I don't understand why it froze".....while there are kids skating on the ponds!
