What are you doing for spare tires? Your tires and wheels aren't exactly common sizes in Africa.
Good luck with the YouTube channel. I manage one myself and it's a great way to connect with like-minded enthusiasts. Just don't get in the habit of making content that encourages people to flame you. The negative comments can wear on you.
How are you documenting the trip? What cameras and computers are you bringing? And why did you choose a JK to live out of for two years?
I'll be running 17" steel rims, and either 33 or 34 inch tires.
I know they are not as common as 16", but talking to people on the ground and who have been there, 17" is by no means impossible to find. All the newer "luxury" land rovers and cruisers have them, so they can be found in the bigger cities.
After much thought, I'm only taking one spare to save on weight, with an ARB plug kit and compressor. Tire repair shops are plentiful, and I found they add to the experience because they are always regular-Joe locals (I had 16 flats Alaska->Argentina)
I've got a DSLR, a GoPro and a laptop for editing. I'm told I'll find fast enough internet in the big cities to upload videos.
I chose the JK because I loved my little TJ, and it had zero problems Alaska->Argentina.
I also like to show other people what's possible, and I think a JK is a great platform because they are plentiful over here, don't cost a lot, and are extremely capable and customizable.
I bet there are more aftermarket parts available for the JK than for any vehicle in history, and the list keeps growing.
The JK also has way more attitude than a boring Troopie or 110
