Tom:
I think the DeLorme Street Atlas software is similar to the Microsoft Streets and Trips software.
We almost exclusively use Google Maps and Allstays for trip planning (along with our GPS to ensure the route doesn't take us under low overpasses/bridges, etc). We like being able to easily switch between map view, satellite view and street view in Google Maps as well as easily see alternate routes.
Some others we've tried...
The Roadtrippers app does a pretty good job of showing lots of interesting things along your route, but not great for mapping and routing.
The Waze app does turn by turn nav, but it's big draw are the community-based aspects of the program, showing traffic, accidents, speed traps, good gas prices, etc that are reported by others in the area and on the road at the time. It also provides alternate routes depending on traffic conditions.
I plan on trying out an interesting app called InRoute this week. It looks to be more route-based (with alternate routing and multi-point waypoint routing).
I always keep an eye on the Technomadia site which is run by tech-savvy bloggers who have been full timing in RV's since around 2005 I think (
www.technomadia.com). They usually list good RV-related software and apps for all kinds of things.
