A concern that I realized a couple days ago is that I don't know if map detail vs memory capacity on the phone will be an issue. I assume it's unrealistic to have pretty much the whole state downloaded when one small area was a 29gb file? That was a topo I downloaded and liked, but if there was a non-topo that left out ONLY the topo data I'd prefer it instead.
You want vector maps, not tile or raster maps. Vector maps are much more compact.
Go to the OSM map site here:
Find the area you are interested in, and check if there is the detail that you want. The area I pointed to is all gravel/dirt & forest roads. But I admit that I don't do a lot of offroad riding, so it may not do what you need.
