I vote for a console-mounted coffeemaker!
I have a 700w invertor (which looks much like the plate shown in the picture) that I picked up at Target. The only thing is, it comes with cables w/battery clamps.
I picked up a coiled cord with a cigarette lighter plug that I'm going to wire up for use in the front or back when needed.
I have thought of a more permanent install though - this looks really sweet. Nice job!
