You can also use a program called Mobile Atlas Creator on your computer to download maps from many free sources and package them for offline use in Oruxmaps (or other apps) on the tablet. These maps can be huge however, since they are raster images (pictures, basically). For a long trip, that could require a lot of storage space, but 64gb micro SD cards have gotten pretty cheap.
I think you would want another app for turn by turn Navigation, but there are many to choose from on Android including TomTom, ALK, Navigon and others. I don't use these but others on the forum do.
Oruxmaps info is here: http://www.oruxmaps.com/index_en.html
Mobile Atlast Creator is here. It has a function to download maps along a route or track, so that might be a good approach when covering a large area.
There really are a lot of other apps out there however, and you might find another that suits your style better.
