2109S Coupler Height and Hitch Ball Size?

[GearHd6]

Hey everyone! I don't currently have this RV yet but the purchase in the works. I'd like to get everything set up that I can before hand which means getting a weight distribution hitch and the correct size ball and then setting the ball height. At this point just hitch ball size is needed to I can order a hitch with the ball.

Thanks for any help!

We have a Flagstaff 21FBRS which is the same model, different name. It has a 2 inch ball. We use an Equalizer hitch and it works really well.

Much appreciated scouter! Hitch ball size was my main concern. Now I can order my Equal-i-zer hitch and ball together.
