This is why I did them. Plain and simple I have 115k HARD miles and my suspension was worn out and now Ill have less sag allowing better front end dynamics when towing and hauling. Nothing more nothing less.

Good mods to help with carrying a load.
Don't get into a back and forth with any rv forums 1/2 ton weight cops on your Ram 1500 capabilities. Many seem to lump all 1/2 ton trucks in the same weight spec pile...or cherry pick your brand truck with a low payload sticker and claim all 1500 Rams have low payloads.

All 2016 Rams/Hemi has the 3900 rawr. Rams Body Builders guide shows the rear axle weights of 2wd vs 4wd is around 60-70 lb difference for the same truck configuration so the rear axles will have close to the same payloads.
You have the truck so scale its F/R axle loads with attention to its rear axle as its carrying all the load.

Just stay within your Rams RAWR numbers (tires/wheels/rear suspensions) and the combo will work fine for your intended use.

On a side note.
I live in the great plains. With small block V8 trucks or my Dodge/Cummins I've found high all day long head winds are worse to pull/worse fuel mpgs than anywhere in 11k+ elevation Rocky mountain passes.
