Thanks for the insight, E. Sounds like the 2nd battery/alternater upgrade might be something I should try to avoid.

So, that said, if I ditch the 2nd battery option and just run a bigger inverter up to my main battery, could I still do it from the back of the VX to the front? Or is that distance possibly too far? Or could I just get away with some heavier guage wire?

Basically, I want to avoid killing my main battery during a camping trip in the middle of the desert. That would be bad.
