Winter Dry Camping
I have a 2003 Kiwi 23B Hybrid. It has exposed FW, B & G tanks. It is a great 3 season trailer as it sits.
I want to set it up to go "dry" camping in subfreezing temperatures (with the sides up!), but am a bit concerned about cold related problems. I've been researching it and have found that if I have an extra $1300 or so dollars sitting around I can get a set-up from UltraHeat that would take care of all my frozen liquid concerns - if I have enough battery power to keep everything running.
The problem is I don't have $1300 sitting around and I only have a single 27M battery.
So, does the minimalist just use a tank heater on the FW tank and then coat that tank with a material like "auto undercoating/roofing tar" (also protecting cold tank from rock strikes when towing); pour a couple of gallons of windshield washer fluid into the black tank; and leave the grey water tank open all the time (or do the windshield fluid trick in there also)? If so, I think I'm still going to need to add a generator to the mix or just the single tank heater is going to use up my battery juice pretty quickly...
Thoughts? Opinions? (Crazy is an acceptable opinion...)
I'm frugal (wife says cheap) and mechanically inclined (I can break anything and fix most of what I break)
