but I never like running things to the near max hence the 19.5 rated at something like 4500-5000 each, much stiffer side wall which adds more than just weight capacity and they supposedly run cooler and longer under heavy loads.
I do understand what you are saying here and I am the same way. But, you are still limited by the 3500 SRW suspension and braking capabilities for that heavy high center-of-gravity load - so you are "running things to the near max."
My son-in-law was in a very similar situation with a 2004 2500 4WD long box. His Arctic Fox camper was slightly heavier than yours. He added all of the things that you have added, including the 19.5 inch wheels / tires. It all made it better, but there was no room for a margin of error while driving it.
After he had done all of these mods, his truck (without the camper) was involved in an accident while waiting at a stop light. The truck was totaled. I told him that sometimes when something bad happens, something better can come out of it. I suggested getting a used 3500 DRW long bed. He ended up with a 2006 model. After his next camping trip, all he could say was, "I just can't believe the difference - and I haven't even done any improvements on the truck!"
As far as a dully, my understanding is that the rear weight capacity axle wise is identical but I would then need a long bed
I think this statement answered my earlier question - you currently have a short bed truck. Another negative when hauling a heavy high center-of-gravity load.
I am not advocating that you buy another truck, just understand (and I think you do) that you are always going to be limited by the suspension capabilities and the braking capacity of your truck. And, one could get into trouble should a necessary abrupt braking and steering maneuver be required. I know that I felt that way when I had my slide-in camper.
