Congratulations on your new LG!
I have (and needed) the interior cabinets and galley shelf for my set up. But the sky is the limit as far as what you can do with an empty cabin. Check out "Hiker Chicks" thread for ideas. In the meantime, I'll give you one.
Your set up lends itself to this unique one of a kind galley/hatch tent designed for the Little Guy. It's special made for a LG dealer in San Diego, where I bought mine. The LG dealership is in a really cool customizing district, so they source out with a few of their neighbors to trick their teardrop's out.
I would think this would really open things up inside and give great cross ventilation.
