In my setup, I framed and boxed in where the batteries are, then used a section of abs pipe with a louverd vent cover on the outside that goes straight through the tub wall (As my battery boxes are inside the two dinette seats) at the highest point in the compartment.

Any recommendations on the style of louver for going to the exterior of the camper?

I actually found them pre-made in the roofing aisle at home depot. They make round soffit louvers caps that have a screen in them that fit perfectly inside of a 2" piece of ABS pipe.

Mine extend past the skin about an inch and a half and I angled the opening just a bit to match the curvature of the aluminum skin on the outside.

As to the subject about watering the batteries, that's very easily taken care of with a water filling cap kit for the batteries themselves.

This method only requires connecting a squeeze ball assembly and inserting the hose into a jug of distilled water and squeezing till the ball becomes first (The battery caps have floats in them that close when the batteries reach ideal water levels).

I am using this method on my rig as well, so I only have to open one compartment up to go and water the batteries periodically.
