I've ran a lot of different lunchboxes in my day. Lock-rite, EZ-locker, Aussie. Snap,crackle,pop behind V8 power and big mud tires. You should be fine with an I-6. I found that an automatic and longer wheelbased rig was easier to drive on the streets in winter over a shortwheelbase rig, and a manual trans. It just takes some getting used to is all. I would have to say that Aussie would get my vote. Their customer service and tech people were really good to me. Good luck with whatever you end up with.
