I ended up working out a spreadsheet that can figure that all out. Empty my rig weights 15100#. Pin weight is just under 3k. (About 23.5%). I expect that percentage to possibly go down as most of our build storage is rearward of the trailer axels.
From what I understand the bags don’t alter the GVWR at all but I use the bags to help ensure my truck sits more or less level once it drop the 3000# on the rear and helps keep the nose from pitching up.
