^ This is spot on. Not letting your eyes take too big a bite for your stomach.
If I was fulltiming In a TC I'd want the room of a longer model with a slide out or 2 and like I said above, a dually is the "right" piece of equipment to haul that.
The flip side to that is if you're going all boondocks on us, you stay somewhere you like for a while, drop the camper and the srw is more handy for 4wheelin but once you get into crew cab, long bed trucks, it's not much better than a dually cause it's sooo long.
Either way, I'd expect good service out of any 1 ton truck srw or drw if you keep the camper somewhat manageable.
That pig of a camper in my sig would ride a lot nicer on a long bed truck with the additional wheel base. I've been comfortable to take it to Alaska and cross country. Wouldn't think twice about doing that long term either.
Out of the box, minimal mods to the truck (suspension, better tires/ wheels) the nod still goes to the dually.
Ideally I'd do the dually and have a small enclosed trailer for some dirt or snow toys, or flat tow a little jeep or something. But now you're talking more $$$$$.
