Keeping our RV water system from freezing
Hey folks, we are about to be taking our 2009 Thor Jazz 2780BH into colder weather (Sunriver, OR) to do some skiing. I've been watching the weather for a few weeks and it typically gets into the singl...

I have seen TTs where they sprayed foam over the tanks that were exposed. Instead of a box spray foam may work as well. Also may be easier and cheaper. Grey water line. I would wrap aluminum tape (Walmart paint dept) to distribute heat then wrap heat tape around grey water line. Just a couple of ideas.
Thanks, those are great ideas.
I think I will put aluminum tape followed by heat tape around the grey and galley lines. I did some more ready and I don't think anti-freeze would help much. If the tank is empty then the anti-freeze would just go into the bottom of the line and stay there. It wouldn't circulate through the rest of the pipe. If the tank isn't empty then the anti-freeze wouldn't make its way down into the pipe.

I like the foam idea but think that gluing some 1 inch sheet foam like they sell at HD for walls might be cheaper than the spray stuff, but might use the spray glue to stick it. They also sell Liquid Nails caulk like adhesive for foam board but would want to be sure it would bond to the poly tank bottom.
Not sure on the discharge tube. The above idea is probably the best but a little costly for such a short trip, though you might be able to remove it and use it again somewhere. If you use antifreeze or rock salt (no experience) I would be wary of over diluting it as you fill up the tanks.
I'll drop by Lowe's and check out their sheet foam. As I said above, the only potential problem is that I might not be able to tape the underbelly back up if I put insulation on it. It feels like the tank pushes right up against it with no give.
I might just put heat tape on the grey and galley pipes and then use a hose instead of fresh water. It's an extra hassle but if it saves me from getting a cracked fresh water tank it would be worth it.
By the way, this won't be a short trip. We'll be in Sunriver for 3 weeks and then probably move down to South Lake Tahoe for more skiing. At least that's the plan...we'll see how the DW handles the cold :)
