Any other pointers for the driveline before I dig in would be appreciated. I've got a few months to go here before I get back home.. I cant wait. Thanks again guys!

If you can run 2000-2100rpms at 75mph it should get great mileage. The sweet spot for towing varies from set up to set up, but 1800-2200 is a good range to shoot for. Randy's ring and pinion has a good gear calculater on their site if you want to play with one.
