just a comment about bike racks on the backs of trailers.
hybrid trailers have no shocks. therefore there's a lot of bouncing inside and outside the trailer. ask anyone who's rode in one while towing, like my wife.
because the weights of the bikes on the rear are held out and AWAY from the bumper, the bouncing creates a pulling back and down on the rack. this constant flexing motion will eventually overcome either the rack's construction or the bumper's welds.
this is different than the spare tire, whose weight is almost inline with the bumper and not held out and away.
since i own a number of bikes worth a lot of money, there's no way i'd risk them in a place that i can't see them or there's a chance that the setup could fail and i'd see thousands of dollars worth of bikes bouncing down the road in my rear view mirror.
