5.0GN tow

My 13 was 5840 with 3/4 of its 36 gal tank, me at 240, a over rail tool box full of gear(100 to 150 easy), heavy rubber bed mat, spray in liner, and my GN hitch, plus my normal gear in cab. So figure around 5400 base weight, which would leave me more payload than Ford called out by 150 or so. This might explain how we so easily stayed within limits.
