On the surface you should be ok. You will also be fine with the 10k hitch. I wouldn't go any bigger on the hitch. The dry weight is your starting weight. Once you add all your stuff you'll have the actual towing weight also known as wet weight. The only difference between your truck with the 8k rating and one like mine with the 10k rating is the gears. It's the same frame, brakes, tranny, everything.
The weak point with our trucks is payload. Watch your tongue weight. Your tongue weight, cargo, hitch weight all count against your payload ratings. If you added a bed liner, step bars, or anything like that, it will also count against your payload. It adds up quick. Get to know your weights, what they are and what they mean. It'll make for a better tow
Congrats and have fun camping.
