No clothes, food, dishes, bedding, camping "stuff" etc etc? That stuff adds up very very fast. I weighed my 3950 with only those types of items and it came in at 16,500 lbs. No water to speak of in any of the tanks, and maybe 10 gallon of fuel in it. It's heavy to begin with and additions add up quick. Pay no attention to published dry weights. Fantasy land. What engine you have in your truck? I pull mine with an '08 F-450 6.4 PSD w/4.30 gears and depending on where I'm traveling, that engine can get a work out. I would have no interest in trying to do it with the V10, "capability" aside. With a loaded truck, including passengers I have about 800 lbs of spare rated capacity left on the rear axle. Axle rating being 9,500 lbs. My pin weight normally runs 4,100 - 4,300 lbs depending on what's loaded and where. If you care at all about rated capacities I'd been surprised if you will be under, with your tires probably being the biggest weak link. Maybe not, but without doing any homework that's my thought.
