Thank you Skip and Sidney for your details. Very helpful. The door sticker in my Ram 3500 Diesel SRW says it has 3,614 lbs payload capacity. Subtracting for passengers and a PullRite hitch leaves approx 3,000 lbs available for pin weight. CC says the base dry pin for the new 34RL is 2,173 lbs so I thought I would be ok with ordering the optional 2nd AC, washer/dryer and Trailair Air Ride pin box. But based on your numbers, I'm clearly wrong! So it looks like the Ram will be towing a bit over its 11,700 GVWR. Ugh!
