SO from what I'm reading it sounds like AC is close to the top of your list, I'd go with a used unit that already has the amenities you want, more hassle to add stuff to a rig that never had it, as Reddog pointed out, they're 100's of used rigs that can work for you and some good deals if you don't mind a 10-15 year old unit.
I think a short class B might be a good option other than a pick up camper.
We just changed to a 5er and I'm either thinking a Portabote or I have a front receiver that I can plug in a tall T bar and add a rack to the cab for either a car topper or a couple of Kayaks but I have not made a decision on either.
