I'd bet your paycheck that hitch isn't set up right! Watch a few Youtube video's how to set it up properly, and make sure your chains didn't strech on your WD if they are that kind. I had to move mine up 2 links once I learned how to properly set it.
Good Luck, keep your Ram. 6000lbs is childs play to this truck.
