Cold as heck the last couple days here in West central PA. Projected to get into the teens last night and we have been preparing to leave for warmer places as soon as our new tires are installed on Friday.
Water in the coach and heat was off. Went out last evening and checked on it. 26 degrees outside and 36 inside. Started up the furnace and it ran for about 3 hours to bring the coach and bays up to 50 inside the coach. I'll just leave heat on until we leave and use it as needed while we travel to keep the bays above freezing if needed.
Concerns about freezing lines while traveling are probably overstated. We traveled to football games for years, a little over 100 miles each way and sat in the cold weather while tailgating and attending the games. Some very cold weather and no freeze problems. Many days that would be over 12 hours and we never experienced freezing issues. Maybe our experience was not typical, but we didn't think so at the time.
