Good point raised on the tow hitch pkg that comes standard. Many (if not most) RAMs come with the class III hitch pkg, but there is a class IV pkg that is technically rated for 10K lbs. even if the truck itself (because it's a crew cab, has 4x4, etc.) is not rated to tow that much.
My Big Horn came equipped with the class IV hitch and the trailer brakes adjust. I sometimes wish I'd have gotten the air ride suspension as that would help minimize sag under load (I tow a 6k lbs boat-trailer combo) and would otherwise improve the ride significantly. Instead, I chose to add the Timbren SES bump stops which replace the factory foam ones. When running unloaded, absolutely no difference in ride. When the boat is attached or I've got 40 bags of mulch in the bed, it makes a huge difference.
