On my 5'er I have 6 12-volt panels set up in 3 24-volt pairs, so I get the best of both worlds. If you had room for 4 panels on the TC, 2 24's would be the way to go. On my TC I have 2 12-v panels in series, and my seat-of-the-pants feeling is that I get better charging than when I had them in parallel.

If you go with an MPPT controller, you can wire your panels in series for 24v to the controller (Actually will be about 34 volts), and the controller will drop it to the proper battery charging voltage without much loss. Higher voltage in the wire means less current, so thinner wire will work. EP Solar makes an MPPT controller that will take up to 100 volts in. You could have 4 panels in series and at 60 volts in, 300 watts would only need 5 amps - well within the capacity of 12 ga. wire.

You are correct 12 Ga is way too small abandon it. I think this is the most important obstacle that you will have to overcome with RV Solar. Just in case you haven't seen these sites before I have included some links:
