Hello! I am new to the forums and have been a Rockwood 2306 owner for several years. We have purchased a Roo 25RS from RVDirect and I want to purchase a new WD hitch before I pick it up in a month or so. I am looking at the Andersen No Sway hitch and it comes with two different sized brackets, 3-4" and 4 3/8" brackets. What size do I need to get for the 2013 Roo frame?
Thank in advance for your help.
