Cross-Country Road Trip in a '68 Barracuda

Sounds like a good trip. Do try to save weight on non-essentials like clothes and snacks <grin>. I think the spare starter is bit much — it weighs a ton and you can buy one anywhere in the US. If you are dubious about the starter, replace it before you start. Definitely carry some other kind of jack — with that much weight in the car the bumper jack would pretzel the bumper before it got a wheel off the ground. I don't think I've ever done a road trip quite that heavy, but I did take 4 people with 4 days luggage plus spares and a toolbox over the high Sierra passes in my fastback. Be kind to your brakes on the downhills is my advice.
