Locker maybe? That is if you go with an air locker.

Also one thing about the power inverter. I've seen some people put the power inverter switch either at the inverter or near the plug in. Since you'll be at either the inverter it self or the plug in suing whatever device you have, you can turn the inverter on there. THis way you won't have to travel to the switch pod, flip it on, and then go back to the inverter or the plug in. It's a thought.
