Just something to add to your thoughts:
A friend with a '96 2500 long bed had a 11' slide-in and had added air bags to keep rear from sagging. He had several bad scares while driving and getting hit by side winds etc and decided that this was a dangerous setup. He was overloaded with that camper (I don't know weight). He was going to get a 3500 to handle this, but did't have the cash on hand or want to get rid of his current truck.
What he ended up doing after all is selling the slide-in camper and getting a used 5th wheeler instead (about 25' or smaller). He also tows a boat behind the 5th wheeler. With the 2500 he likes this setup much better than his slide-in, more stable going down the road. This setup is legal in Utah (double trailers) but is not in all states so research if considering this.
Personally I would not go anything bigger than a 8' poptop camper on a 2500, but I just can't stand the feel of a top-heavy load. As I am sure your figured out by now, a big slide in camper is very heavy, and will weight much more than the listed dry weight once you're ready to hit the road. This weight is quite high off of the ground (worse with 4x4) and increases the roll-over risk of the vehicle. Be careful in your choice.
