I have a solution for this issue. Load everything up to traveling loads, adjust the WD bars so that the rig is level, particularly the TV, and weight each axle seperately. The next step is compare each axle weight do determine that the tires and the individual axles are not over loaded per the manufacturer's specs. Keep track of all of the components involved by close inspections concentrating on wear items and structural cracks before each trip. Enjoy your new RV. The load distribution details of the total rig and the published highway spec are way too complicated to reach any conclusions on a forum.
