Yeah, there's people on here that have only one way of doing things...their way.
I wouldn't rule out a decent camper for your 2500. I have a Bigfoot and am partial to them. There is no drop down behind the tailgate so getting to your hitch isn't as bad a problem. An extended tongue is a good idea that solves the leverage issue. Downside of a Bigfoot is the shorter sleeping bed....it's a "short queen". Not an issue with me as I'm 5'7". If you're much taller it could be a problem. Look at the non-basement Bigfoot 1500 series or a comparable Northern Lite, both made for cold camping.
And do your research on what the camper really weighs. It is usually more.
