I use Basecamp to plan, store and send/receive route data to/from the GPS's. I use Basecamp, along with Google Maps, to find fuel stops, as both come up with different data. My girlfriends bike has a very small fuel tank and we travel a lot through the western states, in the middle of the night, on the roads less traveled, making planned fuel stops a must. It also has a lot to do with what hardware your using.
