Electrical ground question(s)
I'm thinking of installing a medium size inverter so I can use my laptop while running on 12V DC. This Power Bright unit is an example of what I'm considering. There's a space under one of the...

Thanks, all.
To respond to some of the issues raised.
So the conversion from watts of inverter output to load on the battery in amps is roughly 10:1? A 150-watt inverter would draw roughly 15 amps?
My battery "bank" is one 12V battery, located under the steps in the front of the coach. The place I'd like to use the laptop (or charge my phone or iPad for that matter) is about 10-12 feet aft of that position, in the dinette. The power center is right there, hence my idea to locate the inverter there. Don, what is that not a good idea? I'm not challenging you, just trying to learn.
The laptop is an Apple MacBook with an early magsafe power connection. It's a 13-inch, aluminum, late 2008 machine.
KD4UPL, I appreciate the nuts and bolts answer to my question. If I understand you, I can attach both the (-) and the chassis ground connections from the inverter to the chassis ground on the converter and be safe and functional. The unused slots in the fuse bank have no fuses, but almost everything else is a 15-amp fuse, to I'm suspecting that's about max.
