We are planning a 6 wk + trip next month.
I have been waiting for the new Garmin 770 RV gps, but the release has been delayed.
I hate to wait until the last minute to buy something in case it becomes defective or some other problem before we leave.

Any ideas on other RV oriented gps?

I still see the Garmin 760 is still available at some places and also the 660.

Any opinions appreciated
