So I have been planning on adding a grey tank as part of doing a full heat trace and insulation job on my palomino PUP for late fall and winter use.
What am I missing ?
JMO, but I'd say you're missing is the fact that folding tent trailers are designed as fair weather campers and of any type of camper are certainly the least suitable for really cold weather camping. Sure, some folks do it but the reality is there are a host of issues you'd be forced to address once outside ambient temperatures are consistently below freezing, not the least of which is how to stay warm and how to protect the tenting, particularly the vinyl windows which will lose any pliability as the temps drop well below freezing. That said, if you insist on proceeding I'd suggest the easiest method of dealing with fresh and grey water in freezing temps is to simply avoid the issue by locating your potable fresh water source and grey water collection
inside the camper rather than outside. 7 gal Aquatainers are ideal for this application as their footprint is only 12" x 12" ... draw from one for fresh water and run the drain from your galley sink to a second - simple.
Here in Ontario we have several campgrounds open for winter camping and although I have friends who do take advantage of it I'm not one of them. A couple do use their entire systems but it is a process and not entirely foolproof, with freeze ups sometimes occurring no matter how well they've prepared. Personally, if were to winter camp I'd avoid the trailer's entire water system completely and simply use a porta potti for a toilet, the campground bath house for showering, a couple of Aquatainers sitting inside the camper from which I could draw fresh water with the pump, and another one temporarily plumbed to accept water from the kitchen galley sink. Obviously the interior temperature of the camper is going to be well above freezing anytime we'd actually be camping so the issue of having to deal with freezing water of any kind simply goes away. Sorry, I just don't see any advantage in going to all this effort to install a grey water tank on a trailer that wasn't designed for it and then have to concern yourself about freezing if used during the winter. :h
