Thanks for the info abut the pads. I think we will get them. We really don't think the tanks are a big concern since ours have never had a problem, but it seems like a good option since we normally camp Sep-Feb in the mountains. Teen temps are very common.
Having had frozen pipes before we are aware of the problems. Actually what froze on us was the faucet and the water pump. Now my husband put a switch in and light bulbs(not CFL) under the sink and by the water pump. When it is cold out we turn them on overnight and it solves the problem. Looks like he will have to do this again and also put in cut off valves for each faucet and shower. When the faucet froze we had no water at all until he replaced the faucet. Needless to say, cut off valves went in very fast.
We don't use heat at night, seems like a waste of propane, we use electric blankets or extra covers. I am normally up first and hate having to turn on the furnace and then climb back into bed. I now have a switch next to me that turns the furnace on. We just set the thermostat, switch the furnace off with the switch, and I flip the switch in the morning, doze off for a few minutes and wake up to a warm trailer.
This will be another option we will add.
This forum is great. One of the reasons we are going with a BH. The support from the company for this forum and the responses one gets.
Thanks
