As norty1 said, lots of new units out there. I recently got the Garmin 1090 RV GPS which has lots of RV specific features, like Gas Stations, food places, RV parks, and of course, you can tell it what you are driving to keep you from low bridges and such. The feature I like the most though, it has a BIG screen I can see clearly when driving lol.
