Forest river hitch ball size
Is a 2 and 5/16 ball standard on most travel trailers. And is standard on Forest river TT's.

It`s a weight thing. I had an Award TT that had a 5k lb GVWR and it had a 2" ball. I also have a 2" ball that has a 7k lb weight rating. but, basically any large TT takes a 2 5/16 ball.
