Heating Question (Cycle on and Off)

X2 on heat loss. We've had a string of RVs over the years and concluded that having double pane window glass made quite a difference in efficiency that translated into much better comfort level including how often the furnaces cycled. We, too, don't let outside temps get in the way of taking the Winne out and in sub-freezing weather it's noticeable how the front glass frosts over (lots of humidity inside an RV) and the double pane doesn't. That's become a must have for us.
