Picture the fiver as a see-saw. Adding weight behind the axles will reduce the pin weight, not add to it. The amount reduced will depend on the distance the weight is placed behind the fulcrum (axles in this case).
For example:-
Move 300# from the truck, assuming 15' in FRONT of the trailer axles
TO 5' behind the trailer axles.
Result will be 100# OFF the pin PLUS 300# off the truck for a total reduction of 400# off the truck rear axle.
Different dimensions will produce a different result in proportion.
