How to Pick Out Proper Ball Mount Rise/Drop for 2017 Ford Expedition

Published 07/19/2018

Question:

We have a 2017 Ford Expedition with HD Towing Package and just purchased a 2018 Airstream 27FB Trailer - can you tell me what the proper ball and mount is that I need? I see 2 5/16inch ball in the manual but no information about the rise or of the mount. Thanks

I attached an FAQ that details how to pick out the correct ball mount. Picking out the correct ball mount will allow your trailer to sit as level as possible. Basically you will first measure the height from the ground to the top of the receiver opening on the hitch while on level ground. Next, you will measure the coupler height from the ground to the bottom of the trailer coupler when the trailer is on level ground.

Next, you will need to compute the difference. If the hitch height is greater than the coupler height the difference is the drop required. If the coupler height is greater the difference is the rise required. You will want to pick the ball mount with the rise/drop closest to the difference.
