Camco makes a similar one that comes with the hose and vent assembly..

Yes, the through-the-wall vent is technically blocked when the camper is closed. Note both those boxes have a top and bottom vent. TM digs out the floor of the storage cubby with a screen underneath to nestle the box in place. They cut off the bottom outlet so it sits flat on the screen. I don’t really know how much ventilation that creates since hydrogen gas will rise upward. If you don’t care about the bottom vent here’s the box without the bottom vent. I don’t think Camco makes one that way.

You will have a helluva time running a vent through the top/roof due to the sliding bed over the top of the rear compartment storage and not to mention the cantilevered folding mechanism of the roof. Also keep in mind that moving the battery/ies to the rear will mess with the balance of the trailer since you are reducing tongue weight.

I’ve yet to find a box for two 6V GC2 batteries with an outlet for a vent hose. I have this one, trying to figure out how to modify it to work in the storage area.

Let me know if you have any other questions.

Shane. I had the 2, 6V, GC@ batteries also. I used the box from allied and it came with a flat top. I cut a 6" square out of the top of the old factory box (which included the vent). I drilled a 2" hole in the new box top and glued & pop-riveted the cut out piece (from the old box top) to the top of my new box.

I think the reason that TM puts in a top and bottom vent was to encourage some circulation and eliminate and low pressure areas.
