I purchased the first version of the Garmin RV GPS, the RV760, a number of years ago. It was a waste of $350. Between "RV accessibility unknown" all the time when you left the Interstate, and the database showing numerous campgrounds miles from where they're actually at the last straw was when it directed me to a bridge that was washed out 5 years prior, that was never going to be rebuilt. It made it to the next spring after one season of use and was then tossed in a drainage ditch somewhere between Beckley and Mullens WV.
