Thanks everyone, I appreciate the input and kind words.
The fresh water tank on this camper is mounted under it and is also exposed, so I'm not sure if running the water from it is going to help any or not.
I think what I will do is unhook the supply hose from my house to the camper just to make sure that those fittings don't freeze, then just leave a faucet open inside the camper to bleed off the pressure, and if any freezing takes place in the low point drains, hopefully with a faucet being opened any expansion can just go up the water pipe. Then right before my wife gets home I'll hook it back up, the sun will be up by then and temps warming up.
I would think the water heater should be OK to be left on in this scenario, the water in it can't go anywhere.
Thoughts?
