So would I be limited by my rear axle rating of 6100 lbs even though my tires are rated at 7500 lbs (3750 X 2)? If so, I would be still very limited on what 5th wheel I could pull. When I weighed my truck with just me and a full tank of diesel it showed 3260 on the rear axle. That leaves under 2800 lbs available for passengers,hitch,and pin weight. That rules out even a lot of the HT towable 5th wheels.
It's not as dire as you think. Only about half of your passenger weight goes on the rear axle. So if you add 400 pounds of passengers you have 2600. Add hitch and you are at about 2400, which should be enough to handle a properly balanced 12K GVWR fifth wheel.
