My 2016 Vengeance 320A didn't come with a ladder for the garage area either. I took the stops out of the lifting rail so the bed comes all the way down on top of the lower bed bench combo. So far I haven't needed to use the beds as a double decker. It did come with a ladder to access the sleeping loft area.
