So I was looking at the vent by the entrance door and took some measurements. It vent is actually more like 1 1/4" if you measure from camper body to end of vent. You need a 5 1/8" x 5 1/2" vent for it to sit surround the entire vent.
However, what we really only need is a screen to cover the vent holes and not the entire frame. If that's the case, this should work as it will sit along the metal edges of the current vent but covers all the holes.

It is 4 1/2" x 4 1/2" x 1 5/16" which is more then enough depth. Reason being if it sits on the metal frame and not surround it on the camper body, you only need a little less then 1" in depth.
