I don't know about the Ram system, but the Ford factory "puck" system does not require a "window frame." Hitches designed for the system fit right into the puck receptacles and latch down without any rail system or other in-bed equipment. MudChurcker is right, though, about all the under-bed brackets and puck latching system.

Correct, dont actually need the window frame, if you buy the hitch to fit the pucks... but if you already own the hitch, the frame acts like an adapter.
I ended up abandoning the pucks and installing the the hitch rails in the bed of the truck for other reasons, thankfully my curt was brand new and the dealer let me return the base.
