You are overloading your rear axle by about 25%.
19.5 tires will add tire strength, but but you can't replace bearings with bigger ones.
Sounds like money is not an issue here, so go for dually and not only drive, but also sleep better.
If you can afford new truck - the cameras and live traffic can make your day sooner or later.
No, he's not.
Tires, wheels and spring capacity are the only things actually overloaded.
OP, it depends how you feel about the truck. I'd slap 19.5s on and roll. Everything but the springs and wheels are the same as a dually.
