with a 3.92 rear differential on your truck, you will be in the neighborhood of #11,000 pound tow rating, if you have the 3.21 you will be in the #8000 pound range..(I have a 2019 RAM 1500 with the 3.21). Take the 8K pound range for our example. 8K#, minus 1300 pounds you can put in the truck, leaves you 6700 pounds of pulling, take the weight of the trailer,(say it's 5500 pounds), add whatever gear and water you load, and the tongue weight, and you are probably right at max towing,(6700), if you only have 2 in the truck, and say 250 pounds of gear, you might only be carrying 600# in the truck, which means that's 700 more pounds you can pull. These are general numbers. you should look up the exact specs for your truck.
