Allworth... any sane person knows the weakest link in the RAWR of a pickup truck is the tires... since the axles themselves on all 2500/3500 pickups are rated somewhere around 10K lbs or more, depending on truck make and year. Do a little research :-). Since the same axle and frame is used in 3/4 and 1 ton trucks, replacing the tires (and adding a leaf spring or air bags) will effectively raise the RAWR and still be well within the actual axle (Dana, AAM,whatever it may be for his truck) rating. Like I said, this is debatable on which rating you wish to use, but staying withing within the RAWR and not overloading the tires is key. If you don't agree with that method, that is your choice. The weight police is out today :-)
