Plan: travel with 4WD from USA through Central America (hot and wet*) and over the Andes (high and cold). Lot of road, and also a lot of bad roads (if any...)

I understand a Landcruiser is the better build Toyota, but 4Runner doesn't seem that bad either. And there are much more 4Runner's in pre-owned market then LC's. (hence also cheaper!)

Question 1: do I really NEED a LC for this trip - or will a 4Runner do just fine? (i.e. survive and without $$$'s on maintenance)

Question 2: is the 4 Runner sold well in Central & South America (for parts and maintenance)? Is the LandCruiser sold well there?

All info on the subject is GREATLY appreciated!!!
