Hi Thomas,
The Roadmaster Tow Dolly # RM-2050-1 requires a 2" hitch ball. Your Thor Omni XG32 was likely built on a Ford F-550 chassis so you should be able to use the Curt Trailer Hitch Receiver # C15845, but would need to doublecheck that you have this chassis and confirm the model year, as well as needing to measure 6" down from the frame to see if the receiver tube is going to clear the rear fascia.
For the ball mount I recommend using a reducer # 325-GH-007 to get the opening size down to 2" and then using the etrailer Adjustable 2-Ball Mount # e66PR. This has up to a 6" drop/rise to help you get to the 18" - 20" height that the dolly needs to be level.
You'll also need a 4-pole trailer connector to transfer your light signals to the lights on the dolly. If you don't have one then you can use the Tekonsha # 18252 and splice it into your factory tail light wiring for the signals.

Hi Thomas, how did things go getting the hitch and ball setup for your Thor Omni and the Roadmaster tow dolly? Did the receiver and ball mount line up well to keep the dolly level? Your update could make it easier for the next person towing with a similar setup.
