Hi, My 48 6400 w/dump grain bed weighed in @9000#. The trailer tips the scales @just shy of 2000#. I towed this combo in 2004 from north central Kansas to Salt Lake with 3/4t Chevy 2wd, 350eng,4sp manual. No problems except miserable fuel economy and 25mph on some of the expressway hills. Dual 7000# axels w/brakes on receiver hitch trailer. Kept load over axels and it was fine. Weights are from truck scales at local dump.
