Ozz, I too will be interested in that new Dometic thermostat. At least (in my opinion) they did one thing right by moving the t'stat location in our 2011 3400 to the wall at the stairs, where there is better air movement, than having it in the corner by the fireplace, where it is "dead air space". Also, I finally figured out that we only have "one" zone. I was thinking I had two, since I discovered a remote sensor in the bedroom ceiling, but discovered that it is simply "averaging" the temps between the main t'stat and that remote sensor.....which is all of about 6 feet from the main stat. SIGH..........
Waynem, I've always known that statement to be......"expert".....ex is an unknown factor, and "spert" (spurt) is a drip under pressure!
