Great news... Looks like you all set-up..
Just for those couple of items I would make the install as easy as possible haha...
My two multi-drop extension cords are attached to the back of the table top and is always ON. Even when we are connected to SHORE POWER. It does have remote control however so I can turn it off it I need to. I basically use this for a re-charging station for the computers and cell phones, VERIZON mifi box, etc and run the Home entertainment items...
The multi-head extension cords looks like they belong there. They also have an ON-OFF switch. I routed the extension cords around things out-of-sight to get to the INVERTER location. Going this route I don't have to worry about 120VAC grounding or working with the attached shore power neutral and grounds etc... I did ground the chassis of the INVERTER in hopes to cut down the existing RFI noise all Inverters have that might interfere with the HDTV, WX Radios, or my Ham Radio items and Police Scanners. Helped alittle bit by grounding the Inverter chassis directly to frame ground...
