I think you said you would have no traveling access to internet for repair guidance. You can pickup a Kindle Fire HD for < $100. Got my 7" for $75 as a refurb from Walmart. Works great. I use free wifi at McDonalds (12,000 of those in the US) and Subway restaurants (30,000) of those. There's gonna be one of these restaurants in just about any town you pass through that has a working stoplight... Equipment: Tire irons. I got the long curved ones and used a hose clamp to secure it to the frame. I carry a manual 10" tire pump and a single 21'' tube and patch kit. I can attest that the 21" tube will work in the 18" rear wheel with no problems. Tools to carry on the bike: I carry every tool I use when working on the bike in the garage, at home. I just carry a smaller version. i.e. I use standard length box wrenches in my garage tool kit, but carry Harbor Freight 4'' box wrenches on the bike. They were cheap and easy to store. Good luck.
