Go West young man, go West!! Back to B.C. and the warmth!!
I read the trip reports in the TC forum and love the pictures, BUT the graphic images of your exploits over the last little while last longer in my mind than all the pictures posted. I certainly hope a chinook blows through for a while to thaw you and the TT out.
I would be inclined to put some rock salt into the black tank. Far cheaper than anti freeze and if it works on the roads here in Ontario it should keep the black tank from freezing. Black tank is all plastic so no fear of it rusting out like vehicle bodies here in Ontario.
Good luck on your ongoing "Misadventures of Bob" book.:B
