Hi Jay,
I've added a route and further useful information to the site today and will be updating over the next few weeks. I've added tyre details as well.
I used a GPS but took downloaded a pdf to a small tablet as backup.
Your question about a water filter - We used purification tablets for tap water until we discovered there had been an outbreak of Cholera. After that we decided to use bottled water as much as possible only using the purification when absolutely left with no choice. The rivers were brown because they were swollen from recent heavy rain and I didn't fancy spending days on the toilet. (Toilet paper was completely unavailable in one town) There wasn't even a napkin to be swiped as an emergency. But enough toilet talk.
The Viazul bus insisted on removing the seat post and the front wheel for transport, other companies may have different policies. Whether or not you could transport your bike in that bodybag remains to be seen. Airlines have their own policies on how they carry bikes and I've got a post about flying with your bike that you may find useful. I've included links to several airlines and their policy pages so it's always up to date.
