I "think" that some RV manufacturers may be trying to provide roof access through a large vent in the ceiling. For instance, certain Earthroamer and Lazy Daze models may include a large vent for this - not sure though. This approach I can kind of buy into.... assuming one is willing to accept the additional risk over time of leaks from a large vent in the ceiling.
Older Lazy Daze RVs, like our 2011, did have a rather large hatch to the roof over the upper bunk. Since 2012 (I think) the large hatch was eliminated and replaced by a standard vent.
