From the ground to the top of the hitch receiver on the TV is 20 inches in my case. The 'hitch ball height' according the AS is 17.75".

Now for the mixed info, some say the 17.75 is measured from the ground to the bottom of the coupler and others say it is from the ground to the top of the coupler (where the top of the ball head would sit). As most know, a typical trailer ball is 3 inches tall. So do I go with a 2.25" drop, or a 5.25" drop on the shank?

Sorry if this is a dumb question, but I can't seem to get a straight answer. When AS says 17.75" hich height, do they mean top of ball or bottom edge of coupler? Makes a difference on which shank size I get.

Thanks again for your insite !
The dimension is to the top of the ball and top of the coupler. I would hope that you are picking up your trailer from a dealer. He should have an assortment of shanks, so you can select the correct one when you have real measurements. Do NOT trust Airstream's numbers---Measure your trailer. I will bet the dimension exceeds 19 1/2 inches.
