When we say Hitch weight, is that the hitch on the truck, or the trailer? If if it's the trailer's hitch, does that mean the weight given in the trailer doesn't include this weight?
The weight of the hitch for a fifth wheel is included in the truck as part of it's ready to roll weight. The ready to roll weight is; truck, driver, passenger, hitch, fuel dogs and all else no trailer. This weight is best determined by scales. The truck has a GVW, for a 3/4 ton about 9,200 #, so from the GVW subtract the ready to roll weight and you have the max pin that you can deal with, the max pin should be a loaded pin not empty. The loaded pin can be computed by finding the pin percent pin/UVW UVW=Unloaded Vech. Weight. Apply that percent to the trailer GVW to find the max loaded pin weight. This description is simple and ignores the rear axle load which may be exceeded in this simplified calculation.
