You have to compare specific products rather than comparing the generic categories of truck vs RV GPS. That's because no two devices have the same feature set.
In general, a truck GPS will allow you to enter truck measurements and weights. The map database will have restrictions on it and theoretically the routing algorithm will incorporate those restrictions based on the measurements and weight.
A truck GPS will typically also use the DOT hazmat classification system for restrictions.
A RV GPS will typically have the same dimension and weights but it's very hit and miss whether it handles propane restrictions.
There will likely also be a difference in the POIs available between truck and RV GPS.
