Our 2015 has two 15k Heat pumps.
Our forward unit has ducting to both ducts, on the drivers side and the passenger side of the AC unit.
Our Bedroom unit only ducts to the passenger side duct. It is not connected to the drivers side duct and I really wished that it was. I poked around and did not see that it was prepped for it, and gave up.
The Bedroom AC/ Heat Pump will blow all the way forward to the middle of the coach, and a little air will bypass the forward AC unit into the drivers side ducting, but not much.
Our big slide, blocks the AC vents on the drivers side of the living area... we open the diversion registers on the forward AC so that air blows out into the living space, not on top of the slide out when it is in travelling mode.
