You need to do some figuring. Your GVW rating will tell you the weight of the camper you can carry. Weigh the truck at a scale now. Add the weight of the camper, making sure you add 50% to the dry weight to get the loaded weight with all your gear. If it will work, that's good for the truck and camper. Now, go to the GCVW spec of the truck...that will tell you the total weight your truck and trailer cannot exceed on the road. Ad the weight of the loaded trailer to the weight of the truck/camper to find out if that number exceeds the rated GCVW rating. Bottom line...you need to meet two specs, not just one. Good luck!
