Just installed basically the same unit in my enclosed trailer build. Are you using the provided fuel tank or did you go a different route?
I bought a jerrycan and put a nipple in the bottom as a fuel cell. Looks kind of cool mounted to the outside of the trailer (if you fab a tank up remember to get a nitrile rubber washer/gasket because diesel will eat most rubber)
You hide your conversion and call it stealth. I put mine out in the open and give it a beer.
