Thor Super C (Chateau/Four Winds) improvements and mods

I actually upgraded my 12v batteries to the largest (physically) I could fit in the existing battery compartment after one of the original batteries died. They definitely hold more juice, but nothing like I'm sure four large 6v batteries can hold. Honestly, the auto-start system is a nice bandaid, since you just turn it on and never have to think about it. But it would be nice to go a bit longer btween auto-starts :)
