Is the height from ground to top of AC units or is it from ground to top of tallest antenna (obviously not the bat wing)?
IIRC it's top of highest rigid structure - A/C or ladder.

I have hit my antenna too many times. It does not bother me. I have not hit my ac units and never hope too. The Tracstar is the tallest thing on my coach so check yours and see if you have an AC or Dish that is the highest. Also, if you are worried you can always dump air before going under a low object if you are going slowly and pulling in or out.
I picked the highest rigid structure on our coach, which happens to be the storage pod above the bedroom, laid a 2X2on top and sticking out the passenger side. Tape measure from bottom of 2X2 to blacktop measures 12' 6". 3 out of the 4 antennas stick up about 12" above that.
NOW you guys have me worried more than ever about overpasses!!
