There's a good reason why Courtfisher's post said to "CALL" rather than email.

Why?

Because you're far more likely to get what you need using the phone. Emails are rarely responded to. Even an email works in this specific case, you might as well get in the habit of phoning instead if you're determined to arrange everything in advance.

Probably you'll find that you need to actually show up to accomplish anything, but I'd be happy to be proven wrong about that. You sound like you know what you want and are accustomed to getting your way. This might not work very well in Latin America or Africa.

Good luck.

I do not speak English well enough to hold a phone conversation.
In addition, the email remains a trace of a phone no.
In an email I ask exactly everything I need and I can get a precise answer: in a phone no.
I've always organized my travels by email (eg ferry from Russia to Korea and Japan), even for visas to take my Italian travel agent I use the email (over the phone) because there are so less chance of errors .
Just because I do not trust the accuracy of people who do not know, this is one more reason to use the email. If a person does not answer me by email, for me it is not reliable and I waste.
Finally, I can be very insistent.
PS: From Brazil today has already received a response.

Fine with me. I'll look forward to hearing how it all works out.

Worth consideration: folks here are answering your questions based on their direct experience. When someone tells you Buenos Aires is easier, you argue. When someone tells you to phone, not email, you argue. Now, maybe you're right on all counts and everyone else is wrong.....but then again maybe not.

I argue with people more experienced than myself all the time. I've found that very often they're correct, and I do better when I listen. That's just me, so take it for whatever it's worth.

In here there are people who have more experience than me in travel outside Europe and thank you for the advice.
My experience as a road trip is limited to all the countries of Europe, half of Asia and North Africa.
I do not pretend to teach those who have traveled to South America what is best.
But one thing I've learned in 14 years and 750,000 km of Gold Wing, I have to understand what I do. I should not do something just because someone told me.
I have to understand. And that someone has to explain it to me.
Once, in Kazakhstan, a Russian biker friend showed me the path "best" way to cross the border with Russia (I came from Samarkand).
He was a trusted person (a friend), expert (motorcyclist for years), lived a few hundred miles from here, had passed that line several times.
He did not use the gps and showed me the way of a Russian paper, and my map was better and I noticed that the road indicated that he was not, in my opinion, the best way, he insisted: "This is the best way, the safest and quiet for you and your bike.
I was incredulous, but how can you not trust a friend, expert rider, a resident of the region?
I trusted and I ended up here:

I came out alone on my own.
Then he excused himself, mortified. Since then I do not trust anyone, if someone tells me that one way is better than me to explain and argue. I trust only what I see and I can explain with logic.
PS: I do not take the plane to Argentina because I want to arrive in Brazil: my round the world will be decided not only shippers.
