My 17 has the high lift axle, 15" wheels and no air.
It measures 8'4" to the top of the Maxxfan. I used a four-foot level to do the measurement.
So, I have to wonder about the claimed 8'7" for the 21 with air. ETI site says 8'7" in the specs; but air is optional so I don't think height includes air.
