Same problem as above. I have about 900 pounds of tongue weight , my 3500 didn’t even notice it and I adjusted my hitch at the scales. I had a hell of a time getting enough tension on the bars for my dual cam. I basically did the best I could but I know I don’t have enough load on the bars to make the DC as effective as it could be. With that said, my new setup is so much more stable than my old one I don’t think it is an issue. I would suggest making sure you have adequate tongue weight and you should be good to go.
Good luck.
