I have the Bell hitch-mounted 2-bike rack and it works great with the hitch I installed. I have to pivot the rack down to open the hatch but it works fine (no rubbing or anything).
It's not the hitch, per se, I'm worried about. Rather, (at least with the Curt hitch) it's how it's attached that bothers me.Installed Yakima Holdup EVO today. With a Mazda hitch receiver which for some reason not even rated as class I. It's got a sticker on it says max load 150lbs and not to be [used] to tow anything.
