I talked to the FR factory and the new Atwood AC units are a couple of inches lower than the older units. Production switched over to Atwood in the spring. The reason FR still lists the height at 12' 2" is that the early 2015 units were this height.
I have a 2016 that is 12' 0" tall (with Atwood 15k AC). The reason I know this is my garage door is 12' 0". I took an inch out of the center by taking out some trim to make it fit.
Having said this, the height can vary slightly unit-to-unit. I measured multiple 28 and 30ds on the dealer's lot that varied by as much as 2 inches (although it is difficult to get an exact measurement with a tape measure on not ideally level ground). Also, note the weight in the coach can affect the height. From Ford's data, approximately 1000 additional pounds on the back axle will lower the chassis by 1". If you put in a full tank of gas plus fill up the water tank you are getting close to this. Lastly, there is tire pressure. From reading the forums here, people run anywhere from 80 to 100 PSI. Dealers run whatever the technicians put in, if they even check it at all.
