I'll tell you what Rob, one of the best things I ever bought for my old 2004 Grandby was that thermal pack. I learned my lesson not to many years after I bought it when I spent a couple of very very cold January nights at the Border Town RV Park in Reno. Nevada. Back then I had a Aus.Shep/Lab Mix named Babe who had bone cancer and the Reno Pet Hospital was going to cut off one of her legs so she could may be make another year. The temps were running in the 0-10 degree range in Reno and we had had lots of snow so I planned to drive up from Susanville the night before and take Babe to the vet in the morning. I pulled in to the park and tried to pop the top but the snow on the roof had frozen solid and I needed ever tool I had to break the roof free. That night I used the thermostat for the first time and set it to around 60 or so and besides not getting much sleep because of it coming on and off all the time it used up about half of the propane in the tank. By the time I got home a few days later I was almost out of propane. I ordered a thermal pack not to much after that. ....and like several others on this site, I learned that you never had to take it out because it worked great in hot weather too! Babe survived the operation and we had eight more months to explore her favorite places.
We had a thread here several years ago that discussed how long a tank should last-about a week depending on what you used it for (also a good argument for solar). If I planned to be really out in the boonies longer, I carried a second tank.
