As almost as much as I like hauling my bikes using a three-rail motorcycle trailer, it's a pain to soundly move it in and out of places, particularly if it's tight and you have to up again (not my partner and i can not get it done!). I'd just prefer an individual hitch carrier on my van if I'm hauling one dirt bike for the track. That way I don't need to bother with running over things or knifing
