GPS is good to back up your route planning when something changes along the way such as a detour and they are not bad for finding food or other services enroute. I have had several different units, mostly Garmin but would not recommend a particular unit. If you have a smart phone with Google maps or Apple maps they work as good or better than most of the stand alone GPS units. I don't see a need for a RV specific unit. Any of the GPS units can lead you into trouble if you blindly follow it - it is not so much an issue with the GPS as the map program installed and how current it is.
