We have a 2003 Dodge 3500 diesel quad cab 4x4 S/B and unless the suspension has really improved in the past 10 years I would not want a 3000+ pound camper behind me. We recently bought a Northstar TC650 pop up and the sticker says that it weighs 1725 pounds with 30 gallons of water and a full propane tank.
With the camper on there is between 1-2 inches of space between the overloads and springs. When we drive there is no doubt that we have a load in the truck's bed.
Per the local dump's scale our truck weighs 7300 pounds empty with 34 gallons of diesel. The GVW is 9900 so the CC is 2600 pounds. Subtract the camper and we have 900 pounds left. Add people, gear, food, and, if you tow, the trailer's tongue weight, and it would be very easy to exceed this.
Personally I would not want to start with a camper that would put me over my GVW as soon as I put it on my truck.
