I have a 2018 321MK so it's very similar to yours. I tow with a 2018 Ram 2500 Crewcab. After visiting the scales, I discovered my pin weight (loaded trailer) is 2376#. With a 3/4 ton, you WILL exceed the GVWR. What I learned from reading this and other forums is to NOT exceed the rear axle or the tires weight capacity. My actual rear axle weight is 5680 (6500 max). With this knowledge, I felt comfortable installing a 46 gallon aux fuel tank in the bed. With full fuel, loaded trailer and passengers, rear axle weight is 6140#. Tows just fine and I added disc brakes to trailer to assist stopping. Having said all that, you can't go wrong with a 1 ton. Good luck.
