Our 30skp has a step between the bathroom/hallway floor and the bedroom floor. The 305sk has a flat floor, meaning the bathroom/hallway floor and the bedroom floor is the same level, no step. Don't know what the FD at the end of the model designation means. Also, the 305sk has an exterior height about eight inches higher than the 30sk

The 30SK may or may not have the Patriot option, the 305 will have it. The 305 will have 16" wheels, higher GVWR, taller roof, flat floor bedroom. Depending on if the 30SK has the Patriot option, the 305 may have many addtional options.
