Use(d) a dual 2" receiver - top got the 4-bike rack, bottom took a Hitch-Haul carrier, which held the Sevylor inflatable canoe. Used that system for 80k miles or more on our "B". Now with the "B+", rigged Suby Forester as a toad, hard boat carries on its roof rack. Cheaper to set up the Suby as a toad than buy the Thule trailer!!! if not taking the toad, hitch system goes back on for bikes and boat. ST
