Dan - I do plan on having something like that, but part of the design requirements I placed on this project was that it needs to sleep the 5 of us on the road - which means I cannot plan on the cargo space being empty. I'm really thinking about doing a large loft over the cargo space with partial dividers so all 3 boys have thier own space. The main reason I was resisting that is the AC unit is currently in the way. But, looking at the install instructions it appears to use the same opening as a regular vent. So, I'll move it closer to the bedroom, plug a vent in its place and be good to go.
