I'd say you better consider using another F word a lot if you go for that F...... We have had 3 Fs in the family and all were lame. A new F350 blew out a clutch in under 5,000 kms and never towed or carried anything heavier than my two parents and there stuff. My parents were caught in California an extra 3 days. I figure in Bolivia you might say months. Those things just aren't sold or used there. If you are going to use the F word go for a Fuso double cab in a two wheel drive. If you are in Canada, you can import a 15 year old double cab 4x4 fuso with low kms and register it here. The double cab is a bit harder to find. Actually there is one for sale by a guy I know on a couple forums. It is a single cab but only has 3,000 kms.
FS- 1991 Mitsubishi FUSO FG (Canter) - Expedition Portal Forums The thing with the Fuso is that they are very dependible, fuel efficient, can haul a lot of crud and are supported around the world. Frankly, I would take a winch equipt 2wd Fuso over any 4x4 Ford, Chev or Dodge product.
