hello there just saw your post about going to africa.
if you search through the dodge 50 forum to find a poster called lr exporter. he is a man who knows everything about dodges but not only that one of his main things is maintaining a fleet of dodge 50s for a kenyan airport.
so i guess he could give you some advice on dodges and the african climate etc etc.
the trip sounds amazing.good luck and fair play
don't forget to post pictures when you get back.
