cgmartine, I have no photos of my inverter install, I can take some but it will be a few days. I'm not sure they would help much since my RV is very different than yours.
My battery is wired, by the manufacturer, to two studs with #2 AWG wire. One is insulated from ground and is the positive connection. The other is ground. I used #12 wire because that is what I had and I only draw about 10A for the inverter. I put a fuse in series with the 12V positive lead connected to the positive stud and ran the 2 wires, the positive from the fuse and a negative wire from the grounded stud, thru the floor to a 12v cigarette lighter receptacle on the dinette seat. That's all there was to it. The wires are about 3 feet long. I plug the inverter into the receptacle and run an extension cord if necessary to the item I want to power.
Hope this helps. I'll try to get some photos in a few days.
