Ram truck hitch

Has anyone had a Molar 5th wheel on the new Ram 3500? I just got one and want to know if others have anything to say about them. I have not used mine for towing yet.
We have this hitch from Mopar. We have traveled approximately 3000 miles this year towing. We have Road Warrior 427 which weighs in at around 19,500 loaded out. Pin weight is about 3750 loaded with a gas golf cart in the garage. We have not experienced an issues with it.
Thanks for your reply. My trailer is only 9500lbs. Hope it rides well with this hitch. Wondering What's the purpose of the rubber insert? Does it put more torque on the pin & pin box?
