I've done a lot of cold weather rv living. During elk season in northern nv, we routinely see temps near zero. A couple of little tricks I do are, foam insulation around the slides, 2" thick stuff from Home Depot. A buddy of mine bought some high dollar foam insulation, cut to fit and numbered it so he can put back in the same spot, and uses velcro strips to hold in place. I just duct tape mine. With the water if you leave the faucet drip, I mean 1 drip every 20 to 30 seconds, will usually keep the line from freezing unless way below zero. If boondocking, we drip it in a pail and dump back in fresh tank, or use for coffee to not waste it. Another trick, instead of paying a Benjamin for a heated hose, go to Home Depot and buy 3/4" pex tubing, hose ends, proper length of heat tape, foam pipe insulation, and duct tape together for an economical heated hose. My last one was under 60 bucks, and will way outlast a heated hose. We lived in our's last winter in SLC, Ut, November till April, with temps down to 25 below and never had a problem. If your toilet dump is right above the drain on the black tank, we leave it open and flush 2 or 3 times, full pots of water. Then when it warms up, flush good with the sani-flush system. I know this will freak out alot of people, but I've never had a problem with frozen dump valves or clogging up the black tank, etc. P.S., we only do this in sustained below freezing weather, when temps are above freezing for the most part, we use the black system as intended.
