Not trying to Justify my weights and the 5th wheel, we're looking at some TT's also. Just want opinions on occasionally being over GVWR.
Your to be commended for finding your trucks separate front and rear axle weights. Too many new folks simply weigh the trucks gross and have no idea about their separate axle/tire loads.
GVWR isn't used in any legal sense for how much load any truck can carry. I would be concerned about staying within any truck RAWR/tire and wheel capacities for carrying hitch loads from a trailer.
The trucks frame strength is rated the same or higher than the sum of the axle ratings.
The trucks total braking performance is the sum of the axle rating which would be 4800 + 4050 = 8850 lbs of braking performance in your case.
Use those GAWRs as its safe and besides you payed for them .... so use them.
