That vent - in the location it is made for - you can see it on a non-modified ext van.
Only problem is - the Rear A/C vent structure keeps that from being used.
Engineering Interns were given the task one afternoon in HQ.
One said, "I forgot about the Ceiling Vent punchout in the roof die set", designing Ext/Fan .
The other said, "Are the Gen II dudes thinking of the A/C system/Ceiling Fan interference when updating the Interior?
Pretty much messed everyone up - that is where the power is too.
Rare to see someone use the designed location. Caulk could use a 'visual stylist' ( maybe a little off the top... ).
