2011 3500 D/A, SRW
If you are willing to purchase a long bed dually the camper options are considerably more favorable for weight and size considerations. In fact, a 450/4500 is not overkill in the truck camper world. Truck campers are all about maneuverability.
In what world do you live? Not even 1% of the campers on the road are sitting on a F-450 class of truck. Guess the other 99% don't know that they need a F-45.
A 2500 truck will safely handle 4000 lbs. in the bed with the right tires and helper springs. The frame and drivetrain and front and rear axles and transmission are identical with the 2011 2500 and 3500 diesel powered trucks. Only difference is the number of leaf springs and this is easily changed to support more weight.
Nitto Terra Grappler and Toyo tires can support 3750 lbs. so the pair at the rear can support 7500 lbs. and less the weight of the truck that still leaves a payload of 4000 lbs. that can be carried. Go to 19.5 rims and tires and the rear tires can handle 8800 lbs. and the payload can be up 5500 lbs. for the same truck with SRW.
Both Northwood and Lance make excellent campers for short bed campers and they are likely to remain in business. There are more used Lance campers available than any other make and you can download brochures from the Lance website for prior years which helps when evaluating a used camper. I bought a 2008 Lance camper in 2011 that originally sold for $1800 and I paid $12,000. The new version of the camper sells in 2014 for over $25,000.
Easiest if you select the camper model(s) you want and then start watching on Craiglist (or using searchtempest.com) and then get your truck ready for adding a camper. For this you would install 4 tie-downs (Torklift or Happijac) and if a Lance, have the local Lance dealer install the receptacle for the Lance plugin for the camper in the forward section of the truck. The plugin provides power to the camper and enables the truck to activate the break, running, and backup lights as well as the turn signal lights in the camper.
That will get you started. Once you have the camper in the truck and had a chance to drive it you can evaluate whether to add more support for the leaf springs, upgrade the tires, upgrade the shocks, add a bed mat, and other items you will find discussed ad naseeum on the various forums. There is also a forum dedicated to Lance camper owners where you can post Lance specific questions.
The manufacturer's camper weight shown on a sticker on the camper is a starting point and best to add 800 lbs. to that weight to have a starting point for the actual load your truck will be carrying.
There is a lot of ignorance as to the "payload" that a pickup truck can safely carry. The manufacturers all calculate a value based on the truck's configuration when it left the factory and the key limitation is the tires and these can be easily change. They also subtract 150 lbs. from the payload value for every passenger seat in the cab so you see a much higher rating for a truck with a regular cab than for the otherwise identical truck with a crew cab.
Quite a few people who venture up to Alaska with campers on pickup trucks do so having replaced the factory rims with 19.5 ones and going to the 19.5 tires which provide more durability on the bad roads on the way to Alaska. This is also where DRW is a disadvantage as tire changes become more of a chore with a DRW truck.
