Hi...
Thanks for the note. Note, just two furnaces. One in the middle of the coach, and one in the rear for mostly the bedroom and master bath area.
I do have two heat tubes I can see. I am not sure if their is a third in the holding tanks area or not as that is more or less closed off.
But so far I am feeling OK about it all. One think I did not even know, and I am 42, is that it goes so cold down south. I really never though the southern end of the Grand Canyon for example got down below 30. You see, I never took into account the elevation.
Heck, we picked this time thinking it would be a great time to go down 66. But it is turning out, it seems we will be COLD DOWN ROUTE 66.
