Hitch Receiver 2" but Blue Ox Apollo Tow-bar is 2.5"

[MIsheeTX]

I'm in the same boat. Prevost 20K hitch with only a 2" receiver. Looked everywhere and called Hitch Pro in Eugene, OR: highest 2" shank is rated at 17K lbs. 2.5" shanks go to 20K lbs.

Strange that Prevost would install a 2" receiver for a 20K hitch.

I'm planning to tow a 26' stacker, max load 19,800.

Hi - Any update on what you had to do to tow the stacker with the 2" receiver? Thanks!
