Winter Camping - How Cold?

[Dogpatch]

I am selling my RV and a guy asked me if he could winter camp in it for a couple of weeks. It gets pretty cold here in Canada periodically in the winter. The specs on my RV say "heated tanks" and "dual pane" windows, but my question would be the water lines and such. Also that the chassis is spray foamed underneath.

How cold is safe?

What R value would the walls and ceiling have in them?

In my opinion, your responsibility as the vendor is to honestly state the facts ( heated tanks, double pane windows, foam insulation, etc.) and the buyer can then decide if MH is suitable.

Is the water/sewer compartment heated that's my opinion were it will freeze first.

In 2006 we sold our house to buy our houseboat. That essentially made us homeless, so we bought a 2004 Challenger 5'er, 36'er, 3 slides, pretty nice digs. It was touted as a "4-season" unit, and for the most part it was... However, the weak link was the plumbing drain valves, which were below the kitchen sink and protruded into "air". When it got below 15° out, we'd lose all water to the kitchen. Not good. Took 1/2 hour with a heat gun to get the ice to melt. I eventually boxed in the bottom with 2" styrofoam, which worked-- up until a 6° morning, and we were froze up again...
