I’m with Perz. Rear double shocks are in my future. Aftermarket shock mounts can easily be added.Take a look at the rear end of my rig going up the Diablo Drop Off just before the moguls. this is with Rancho 9K’s with 4K miles on them.

I built my own suspension with 8 leaves on the rear with Stable Loads:
3-leaves in the upper secondary pack aka overload pack
4-stock leaves in the main pack with the actual overload spring and a 2000 pound helper spring over that giving a 3 inch lift to rear axle.
