I have a 08 keystone hornet 27dbs that I camp in the winter months during hunting season. Unfortunately I do not have a power or water source. I do use a generator for power and would like to use the campers water system. I am curious if I can add a potable antifreeze to make the camper functional. I probably would still bring in drinking and cooking water but it would be nice to use it to shower and for the toilet. Is this a possible scenario? What ratio of antifreeze would it take to keep it from freezing? I could still blow out the pipes and put antifreeze in the traps when I leave I just don't want to freeze the tank. I am in central alabama so the winters are not as harsh as some but it will sometimes get in the teens. I could drain it on the rare single digit occasions if needed.

I could be wrong - but really ... Alabama and you're worried about 50+ gallons of water turning rock hard? I personally think you are worrying over nothing. A few slight dips below 32 degrees isn't going to matter especially if it warms back up during the day. Now up here in Montana when it gets -20 degrees for 2 weeks straight is a different story. Point is that it takes quite a while for so much water to actually freeze to the point it would do damage. Worst case for you is 50 gallons turns to a bit of slush. You would need sustained deep freezing temps to hurt your tank.

So relax and a fill the water tank up and enjoy your rig.

What happens when the water freezes in those little PEX lines? Or in the water pump? Or in those little plastic valves? etc. etc. etc.

Again, the poster lives in Alabama. I would be surprised if the average LOW is less than 40 in Nov-Mar. If the weather does drop below 32 then it would only be for a few hours at night and during the day it would warm back to 60-70 degrees.

No harm will be had in the water lines or pump at those temps for a few hours.
