Awesome plan will be following.
I want do do the same journey but basically start from home on the east coast and head south to Argentina. My plan is to take a 4x4 truck with a nice camper shell on the back with a folding cot in the camper shell. I'd have to bring my bike also like you did.
Check out www.theroadchoseme.com Pretty much the same story and the guy drove a TJ also. A great informative read and inspiration if you get the chance.
My jeep. I doubt she will make the south america trip
Thank you. Is your jeep manual or automatic?
