Payload is an issue w half tons but even bigger limiting /related factor is rear GAWR. Unless your pulling a boat with no pin weight or NH3 trailer with r & r axles there is no way u can pull 10,000 plus without exceeding rear axle #. 3/4 tons especially loaded diesels will often have similar or slightly higher payload sticker #, they will have much higher rear axle GAWR #. So pending how weight is carried, you will have more flexibility. And given full floater vs not... far more real world strength in the hd axle.
