Tim, The link does say that and the instruction say to as well... http://sitepro12.sitepro.com/masterlibrary/11327/installsheet/CM_11327_INS.pdf crb, it is supposedly is rated for 1000lbs. Uhaul motorcycle trailer is 550 and bike is 430 wet so I would be right at the limit. It is any automatic as well... how much lighter are the harbor freight trailers?
