Hello all, new member here. I weighed my 2015 F350 dually and 2015 V4000 today and thought I would post the numbers for anyone interested. The first weights are with the truck, fifth wheel hitch, transfer tank and 125 gallons of Diesel. The second set of weights are with all of the above plus the trailer with folding chairs and basic tools in the basement, 50 gallons of gasoline and about 10 gallons of water.
With around 935 lb of Diesel and 206 lb for the B&W Companion hitch my truck with the empty transfer tank and not much else weighs 8479 lb if my math is right. The hitch weight of the V4000 works out to 3520 lb and the trailer weighs 16377 lb, taking out the water and gas it is closer to 15982 lb.
