Great descriptions/pics, and this do-it-yourselfer especially appreciates the included pricing- thanks!
Question about the 4-bike rack add-on:
I see a "warning label" in the pic of the receiver but can't quite read it- seems to be about what bumpers it can go on etc. And I know some bike racks carry similar warnings, usually relating to use on trailer bumpers. Question being, what sort of reinforcing (if any) did you have to do to the bumper in order to prevent the dread "load of bikes in the road" we sometimes read about here?
