Wiring for inverter

We purchased a 3.2 cubic foot upright freezer for the fiver. I have a 500 watt (1000 watt surge) inverter that I want to run it on while on the road. Here is what I have calculated. The freezer draws almost 2 amps or around 240 watts. It will approximately double that on start up. The inverter will draw about 10 amps on the dc side for every 100 watts output. I plan to run the wire from the terminal block above the battery back to the kitchen cabinets. From what I can find on line, #8 wire will carry the current, but with the length (around 25 feet) I will be running, I am thinking maybe #6 wire. Any input appreciated.
