Just today I looked at a Ram 2500, 4x4, diesel, crewcab...Tradesman . Total payload was only a bit over 2000 pounds. Not much left for pin weight when yo7 add weight of hitch, passengers and stuff. The exact same truck with a 6.4L gas motor was a bit over 3000.
You need to look at yellow sticker on drivers side door jam and deduct passengers, hitch weight and stuff.....what is left is legal pin weight.
