CWSWine has a similar truck and same RR axle rating, and weighed his truck at 3220 on RR axle without hitch? or other cargo. This would indicate a real world 3000# kingpin weight limit, vs the rating of 3500#.

Your on the right track here but the 3000 lb number would be the remaining "payload" and not a king pin weight limit.
I doubt any 2500 Dmax/A has a 3500 lb payload. Most 2500 trucks rear axle weigh in the 3000 lb range from the factory which leaves around 3200 lb for a payload.

Now once the truck owner loads his necessary junk in the truck then those figures will change. Some guys load the truck down heavy and others may carry a small 25 lb bag of tools.

I would concentrate on the trailers dry weights/CCC/ GVWRs and forget about posting lengths. Some folks have it in their heads a certain size truck can only pull a certain length trailer.

At 13500 GVWR and a 9180 dry gross means around 4320 lb CCC. Most folks don't pull around a empty trailer not will you load 4300 lb of stuff in the trailer. Generally folks that just RV may add 1500 lbs to this size trailer = around a 11000-11500 lb trailer. With a 20 percent hitch weight may have around a 2200-2400 lb wet pin weight.

looks like a good match if the trailers brochure weights are correct.

I pull a 11200 lb trailer with a 2500 Dodge/Cummins. My hitch weight runs in the 2200-2400 lb range depending on how we load the trailer = 5100-5200 load on the trucks 6000 RAWR. No problems there.
