I spent the last two weeks reading your RR and loved it!
It's hard to say how much your RR captivated me, even if I could write you in Portuguese. Your trip isn't so different from the ones I used to do here in Brazil. At least in terms of "no-ideal-bike for a long trip" and "no planning at all".
As someone has already said, your RR can be named as "LR" (Life Report). Your writing style is amazing and I think you could produce not only one, but two books: one about the story of the trip and the other one made only with the photos.
I root for your health.
