Hi, Bill. It does already have an EMS installed. Dealer said that all I need is to install 3rd unit. Having never had an EMS before, I wasn’t sure how they work. I talked with an owner of a 2018 Winnebago Grand Tour MH that had 3 units and he said he couldn’t run all 3 at once. The front ac seems to be dedicated to the bedroom. Going to try closing down bedroom vents this weekend to see if more air will go to main cabin. At 68 deg setting, bedroom stays cool, main cabin struggles at 75 degs. That’s with bedroom vents full open.
