I went to a suspension shop they put a extra spring on each side rear, on my dodge 3500 I hauled a 5500 lb camper with that setup
THIS ^.
If a guy want's the RIGHT setup to haul heavy weights and does not mind the unladen ride. Get a set of Deaver heavy duty springs or any good variant of additional leaf springs. Bolt those suckers in and have a great day with no sway!
That's how I used to do it on our landscape trucks. Most of the old 3/4 tons we had got junkyard dually springs with the overloads. Cheap solid upgrades back in the day and still a very viable option for those that prioritize spring rate over empty ride.
