Understand you have decided not to upgrade, but keep these couple O' thoughts around JIC you decide to UG your TV:
Forget the V8s - they are ancient technology! Look at the Ecoboost Engine. Our F150 (special order/equipped) can tow 11,700!
While not a true 4 season, park it in a snowbank 5er, our rig (and by extension the one you were looking at I believe) are completely sealed and "insulated" underneath. I use quotes because it is minimal insulation, not what i would callsub-zero insulation. also, the 5er is a ultralight (that's why you can tow it with a 1/2 ton
) so the walls and ceiling will not be heavily insulated like the big rigs towed by the 3/4 & 1T TVs are.
Having said that, with the tank heaters on and if you get the optional fireplace to use with your furnace, I think you would be OK for a few days in a cold climate. Proviso here is location and wind. You want to stay out of the wind as much as possible.
Two more things: if you do this, buy some pipe insulation for your city water hose (if it were me, I would operate off of my fresh water tank and just fill as needed though) and make absolutely sure every time you dump your tanks to the sewer that your outsice sewer hose is completely clear of fliud.
