If you use the GPS in your RV and you travel in places where there is a potential for a route to take you under an overpass that is too low for your RV then you need a Truck or RV specific GPS unless you are aware in advance of where those low overpasses are and you re-route yourself. The usual argument that one can install a POI file to point out low overpasses does not hold when you are already on a road with a low overpass with no way to turn around or exit the road.

The Rand McNally RV GPS lets you put in if you are carrying propane and routes around roads that are propane restricted. None of the other standalone RV GPS units do that. The Garmin Truck GPS - Dezl series - does have a propane/gas setting in truck mode.
Again, if you never travel where this could be a problem then a car GPS will do just fine.
