Yes Ray, that was our bus, it was 53 inside the bus at about 5AM, I had the heat side of the cruise airs set to 68 when we went to bed. The outside air temp was 41 on my SMX when I looked. The next night I used the base board electric heat but I think the Webasco is the way to go.
I am going to see if there is a reason to let it go down to about 35, that will take care of all our needs. I will let you know what I find out.
