The max you can put in it is on the door sticker. How you get to that number is up to you. Your RAWR is 6000lbs per Rams towing guide. Your payload is around 23-2400lbs. FWIW I tow a 5'er that has a dry pin of 1385lbs. All loaded and with a B&W Patriot my pin is somewhere between 17-1800lbs depending on water. If I use the trucks payload then I'm real close to my 2176lbs with everything else in. If I use the trucks RAWR of 6000lbs then as of the last weigh in I'm at 4900lbs on the rear axle. 1100lbs under.
If you're looking at dry brochure pin weights of 17-2000lbs then it's a very good chance you'll be over the trucks payload, but still under the trucks RAWR. For your short trips I'd do it. But remember you max tow rating is 10,500.
