Hitch Ball Size

[ssfreedom]

I am thinking of buying an Rockwall A122HB. What size hitch ball is required?
Thanks.

Don't know exactly if this is true (the dealer told me this....) I know that my A128s uses a 2" ball and I believe a they indicated that all of the units use a 2" ball.

Since it was my dealer, I believe that I have 30% chance of being correct!

Mine is also a 2" ball on my A128S but when I had my Jayco P/U, I needed a
2 5/16 " ball. Must be a manufacturer thing about what size they use.

My unit is the largest (longest & heaviest) in the FR A-frames. Because it has a gear deck and capable of carrying more weight, it requires a class IV hitch with a 2 5/16 ball. I have the Forest River T12SDTH which is (I think) equivalent to the Rockwood A127TH
