Yip, I’m in a similar boat. Kids off school for a fortnight so we went to our caravan on Friday night. Water feed pipe was fully frozen (I’d drained down the system so no problems my side of the valve) and it also looks like the gas regulator valve has moisture in and has frozen, so no cooking/ boiler etc.
I ended up flushing the toilet with a bucket of water from the river, a very cold experience.
Ended up coming home on Saturday. I too am watching the forecast with interest, hopefully we can get up after this weekend for a few days.
To sour things a bit more, the wife has suggested if the weather doesn’t get any better, then I fit the new bathroom suite instead!
