Phone charging was something on my list of things to figure out. I think I could add a 12v socket pretty easily, that's a great idea.
As far as the 6th gear unlock, I'll have to bring that up next time I speak with him. I saw in some of his older posts that he has a connection that does it for $500, at least on some of the buses he was selling last year. If it really does net 2 mpg then it would break even in about 3500 miles, half of which is on this drive home.
Also, just want to give a big thank you
to all of you that have contributed your invaluable advice to me over this past week. I'm grateful for folks that are willing to share their knowledge with those that are eager to learn.
