The magic number is GCVWR. That is the combined weight of the truck and camper. (Gross Combined Vehicle Weight Ratio). Now, whatever the truck weighs, subtract that from the 15,000 pounds rating, and you get your max camper weight. (to an extent). There again, in order to run max numbers, you won't have anything in the truck, not wife, kids, or dog, or firewood.
Don't know the specs on your truck, but a 2 wheel drive, around 5200~5500 or so, a 4x4, over 6000. That leaves about 9000 for a camper MAYBE. The camper you picked will be at 7000 or more with options. Add another several hundred for gadgets, clothes, food, beer, and then 1000 for toys in the back, and you are at 9000 for the camper. And while it may pull it, you won't like the gas mileage. (no I don't have one, but that V6 is going to work). You're also going to kick the tongue weight to around 1500 pounds, may be more than rear axle wants on your truck, and I know the springs won't take it. I have a toy hauler with 1000 pound tongue weight, and a 1/2 ton Ford. I was going to move it across the yard one day without the WD hitch. That didn't work.
Now really, I'm not trying to rain on your parade, and all of these numbers are guesses and estimates.
