Round bars

Using exactly the same WD hitch and round bars, it didn't evenly distribute on my current tow vehicle 2015 Ram 2500 Cummins tradesman longbed crewcab. The rear went down more than the front. I didn't bother much because my tow vehicle is already much much larger & powerful. But still.

With the big heavy Cummins up front and a truck designed to carry weight in the back, how much weight do you really want to redistribute? 1000 pounds tongue weight is nothing on a Ram 2500, not even close to payload ratings. The only thing I would double check is the stock receiver to be sure it can handle the weight of the tongue and it might be in your best interest to get an aftermarket receiver so you can tow w/o weight distribution should that work better for you. Adding 1000 or so pounds to the rear of the truck will actually made it handle better, not worse than stock. Weight distribution is to add back to the front axle a certain percentage of weight taken off by the tongue weight. With the diesel weight and with the stock unloaded front/rear weight bias favoring the front axle adding to the rear only makes thing better, not worse.
