After 3 years it still performing better than any bus or coach I've been in both summer and winter has been a comfort but we have 3.5 tons total heat pumps. Arch and Hank did the ducted unit unit and I used internal evaporators. The unit in the bedroom of the Newell is 1.5 tons and if I had to do it over again I would go with 9k btu as its way to cold in there even in the summer at 105 oust side temp. If you go with a ducted unit make sure its a high CFM airflow as the ductwork can slow the velocity of air. Our Prevost bus is 2 ton with 3 zones and its perfect but its only 40 feet long and NO slides, it also has 3 internal evaporators.
