I just wish Dodge would make a one ton single rear wheel reg. cab pick up
As JPF59 said they do. The catch is it is only available in the bottom Tradesman or SLT, neither of which have leather seats or all the other do-dads.
If you want 19.5" tires stock, check out the chassis cab. Would mean you would have to do something with the bed and the extra 4" in wheelbase.
The longer the wheel base the easier a vehicle will handle a load and the smoother the ride, all just plain physics. The longer wheelbase will reduce the chance of porposing. The longer wheelbase will also reduce the effect of the load from changing the weight on the front axle. If the COG is in front of the axle, more weight will be placed on the front axle of a short wheel base truck. If the COG is behind the axle, more weight will be removed.
So yes, a short wheel base truck will handle the camper just fine if it is within the payload capacity of the truck but at the cost of a slightly bouncier more bronco-ish ride.
However, it is only the wife and me but we still went with a CC. We put the grill, leveling blocks, chairs, umbrellas in the back seat. And we still have a place to throw out coats, snacks, and other misc items.
