I have a Fox Mountain 5th wheel.....built by Northwood Mfg. so it's an "all seasons" trailer with heated holding tanks, plumbing up in heated space (provided the heater is on), thermal pane windows, etc. Just a few more years before we both retire but I have a dream of spending some time up in Yellowstone in the winter, watching the wolves play in the snow. Anybody camped in the snow? Anybody done it in Yellowstone? What's your experiences?
