Hey, Saw your thread when you started, now you're ready to go, Awesome Just remember you won't be in Canada anymore, it is the land of thieves down here. If it can be stolen it will be. Please make sure you have an alarm with an immobilizer, double or even triple lug nut locks on every wheel, even the spare, swing arm lock, weld the nuts on your winch. Make sure you always pay to park in a lot with security and a big wall around it (many places aren't made for tall vehicles). Oh, and the regular Toyota door locks can be beat in seconds, most people have deadbolt style lock cylinders installed in place of the stock ones to slow the thieves down. Get a steering wheel club too.
The first place you find that will install the window security film, do it, makes it a little harder for them to do the smash and grab. Make stealing frustrating for the thieves and they will leave you alone, maybe, but gringo is always a target. 99% of the people are great, but 50% are opportunists.
I'm in Peru and have seen it all. Nothing surprises me anymore. I live along the Pan Am in Arequipa, southern Peru. Look me up when you make it down here.
And don't forget it is okay to offer a "gift" to an official to make things go smoother or go away.
Have an awesome trip!! Que vayas con Dios
