Hi Guys! This is my first time, so please be gentle. I haven't seen anything on this topic in the search feature. I want to put a hitch on my '92 Mazda MPV to carry a tandem bicycle. The bike racks come in sizes to fit 2" or 1 1/4" hitches. Has anyone had any experience with these and what size hitch would you recommend? I'm leaning toward the 2" as the tandem is a little on the heavy side and I think it might be a little sturdier than the 1 1/4". Thanks.
