dle,
We have a 2010 ElkRidge 34QSRL. We like to go skiing. Our first experience was Santa Fe, NM for a week, and we did fine... Even when it snowed. But the temps were above freezing during the day. We ran off our fresh tank for water, filled during the day when warmer.
Our second experience was Durango, CO for 10 days. We got 13" of snow and temps at -26*. We had frozen fresh pipes, even though we had a light pointed at the UDC for warmth and the furnace running non-stop. We had supplemental forced-air heaters inside as well. We had lots of condensation on the inside of slides, that froze. We ran off fresh tank water, filled daily during the day.
We added tank heater, pipe heaters, eliminated the low-point drains on kitchen pipes, insulated all pec runs we could see, wrapped as much of drainpipes as we could with insulating wrap.
Our third trip was Breckenridge, Co for 10 days, temps in the 20s and teens...and we had no issues with pipes, but still had condensation inside. We added a small electric fireplace, which helped overall. Ran off fresh tank., filled daily during the day. Much harder when temp isn't above freezing!
I would consider a rig more suited for full-time use like a Big Horn, Big Country or Landmark. Definitely get dual-pane windows and Yetti package as well.
It will still be a bit of a challenge, But those rigs have a better starting point.
