Airhead Vent Outlet

[pdg978]

I'm in the process of installing an Airhead composting toilet in our 2014 Sprinter. Since we have a penthouse top and are installing in a shower enclosure I think our best option is to vent it out the side. My question is what do people recommend for a vent cover on the outside wall of the van? The fan for the Airhead vent line is right at the wall and needs some protection from rain/snow etc. It seems that some type of clamshell style cowling would work but I'm looking for suggestions. Thanks for any help!

I am not familiar with this specific setup but I would strongly recommend venting through the floor if possible. That's the way Airstream did it on the old trailers, not sure about now. Unless you plan on fording lots of water a floor vent is much better than a wall penetration.

The unit is mounted in the shower pan and there is no easy way to vent through the floor without compromising the shower. I agree that through the floor might be the best option otherwise. Thanks.

I have to wonder what smells are emitted out the vent? I would expect the higher the vent was, the better.
