"by the book", the camper you are talking about is 1600lbs OVER the recommended load of the vehicle before you even filled the water tanks...
That being said, its your truck. Even with the 2.6, you may find the performance a bit sluggish with that much camper on it's back. I just took my 88 2.6L 4x4 from Boise to Seattle with just over 1,000 lbs of Harley and misc tools in the back and I could really feel the load. The trip went fine, but you are talking about 3 times the weight. You might want to consider a lighter camper or a full size truck.
