The guy that bought my Torque TH had a Dodge with the puck system. I included my old B&W Patriot in the sale because I upgraded to a B&W OEM Companion for my Ford. He bought a "picture frame" adapter that fit the Dodge pucks and had slots that the Patriot and I believe other rail style hitches fit. This adapter may give you some more choices for a lighter hitch?
The Ford B&W OEM is 75 lbs on top & 75 lbs on the bottom, it seems the Dodge pucks are spread out further so the base weighs more??? When I pull my hitch I back the truck down on the TH garage door which is at the same height, so I can step the hitch into the TH garage. I set it on a wood pallet so the pucks don't mar the floor.
