26U WDH Shank

[MWBishop]

Need to order a WDH and shank for towing 26U with F250, but have no idea what shank to get. The Equal-i-zer has a handy calculator to determine the correct shank, but it assumes having all measurements and I am missing one.

So, for a level 26U (or likely 25, 27, 28 is same) can anyone tell me the distance (inches) from the ground to the top of the socket where the hitch ball fits into the coupler? Not exactly a number I can guess...

Thanks.

The service mgr at Colonial told me the following:

An Airstream trailer requires a ball height of 19-3/4 to 20 inches (that is, the measurement of the ground to the very top of the tow ball while installed and set up on the truck).

MW, wish I could remember but mine is in storage. I did measure my ball on back of my truck and it's at 21" from the ground. I drop the trailer on the ball and it levels out nicely.
