I thought about that and googled it, yes guys are running plows on the 5200 LB axles. Probably my crew cab is contributing to some of that weight, and my fat ****! I have seen reference to a 5,600 Lb axle but not sure if that includes 99-03 SD

Ive got a full ranch hand front bumper and custom steps on my crew cab. Batteries have been relocated so that helps some but I believe I’m in the shame boat as you, very very close to my sticker axle weight with just me, my crap i keep in the cab and a mostly full tank.

I can tell you I put stronger springs in the front after the old ones sagged, and the ride vastly improved.

Many states have (stiff) annual gross weight registration fees.
That may have something to do with why some older dually trucks have only 11,880 lbs GVWR in the door sticker?

I don't remember max rating for Dana 80 dually axle, but the four rear tires are rated for up to 11,112 lbs.

The 7.3 also takes away from payload.

I have not weighed mine yet. Partly due to not getting by a weigh station (an hour out of my way), and partly due to the cost of filling my 67 gallon aftermarket fuel tank.

I also have heavy wheels and tires, larger front brakes, front brush guard with winch, and an aftermarket rear bumper too. Probably have about the same remaining capacity as you, or less.

That said, I have carried 3,600 pounds in the bed. Self-limiting to 3,000 going forward as that makes my rear spring pack "flat" rather than reverse-arched. And it drives just fine.

I know, I know, I need to get it weighed. It is probably also a 1/2 ton pickup, F350 badges notwithstanding.
