With that extended run tank you should be able to make it all the way out to Nebraska for the Central Plains Regional Rally in July this year! You won't need the generators but I can promise some good times and even better food! I'm sure you're interested in that!
From here you have the Whole Wild Wild West to investigate!
YOu'll like those LEDs from Michael. I put mine in when we were down in Florida and had to run the slides in and out several times (thanks to the advise of John K) to get the converter wizard to show us the lights and that it was working with the battery and that included having ALL of the 12 volt lights on too! Great things those LEDs!
