Thanks all for the input so far lots of useful info. What I am going to do is basically tour most of the countries on the continent, except Venezuela and those tiny 3 countries that are sandwiched between Brazil and Venezuela, over the span of about a year. Will spend a lot of time on paved roads but also dirt roads and probably just dirt and sand, since I'll be doing a lot of wildcamping. After that I'll tour every country in Central America.

Are you talking cities that number in the millions like Buenos Aires and Santiago or also cities that number (a few) 100k, like Bariloche, Puerto Mont, Valdivia etc? If you can only get them in the really huge cities, that may not be enough, since they are often thousands of miles apart in that part of the world.
