Bill and Mike I respectfully suggest we are talking about two different things here. If one is interested in the trailer pin weight, which is a dead weight not subject to dynamic forces such as CG, then the entire vehicle weight differences should be used to determine that weight. The total weight applied to the truck when hitched is the pin weight and it doesn't matter where that weight is distributed on the tow vehicle.

If we are discussing dynamic loading on the tow vehicle axles then weight transfer comes into play and CG can be a factor. So can pot holes in the road. This would not be an easy calculation to make.

Both sets of information are important but they are different.
