The 1160# is figured by accounting for weight of myself, the gal, the son, the kid seat, the dog, and the tonneau cover.
Is your RAWR 4050? I bet this would be pushing that too... hmm.
Looking at Fleet Ford weight specs shows a '13 F150 super crew 3.5 eb engine 145" wheelbase has a small 3850 lb RAWR (7100 GVWR).
Its going to be carrying all the hitch load/stuff in the bed and a percentage of rear seat load so its going to be the biggest safety factor.
Run some estimated weight numbers at you shows these trucks can weigh in the 2400-2500 lb range on the rear axle. Now subtract that from 3850 RAWR leaves the truck with a estimated 1350 lbs for a max rear axle payload.
You have the truck so drop by a set of scales and get the trucks front and rear axle weights. This way you know how to set up the weight bars and more importantly if that 11000 lb toy hauler that can have 12-15 percent hitch load will exceed those 3850 RAWR numbers.
RAWR = tires/wheels and rear suspension.
The '13 F150 comes with several RAWR numbers (3500/3800/3850/4050/4800) and GVWR ranging from 6450 up to 8200 lbs.
So which F150 you have depend on GVWR and especially RAWR numbers as its carrying the load.
