6 or 8 AWG is much too small unless your inverter will be within about 2 ft. from the batteries.
Plugging the shore cable directly to the inverter output will work fins so long as you always remember to turn off the converter. I wired mine that way, and all was well until the day I forgot to turn it off. The batteries ran down real quick.
I ended up connecting the coil of a normally closed relay to the inverter output. Then I used the contacts to interrupt the power to the converter. Now, turning on the inverter automatically turns the converter. To monitor the state of things, I wired a red neon pilot light across the relay coil, and a green on across the converter.
