I didn’t get the factory puck system so I got the B&W turnover ball with companion hitch. It’s a good hitch and I recommend it. Whatever hitch you get make sure it will handle your RV weight.
My RV has the flex air pin box which makes for smooth towing. Did you have the option to get an air suspended pin box?
