Question:
I will using this adapter with a set of Rock Tamers by mounting the Rock Tamers to the larger portion of the adapter. What is the outside tubing size of the larger section of the adapter, 2-1/2” or 3”? Thanks.

Hi Dan; the outside tubing on the Roadmaster Anti-Rattle Hitch Extender # RM-071-1075 is 2-1/2" x 2-1/2" so you would need the Rock Tamers Heavy-Duty, Adjustable Mud Flap System for 2-1/2" Hitches # ERT00110.
