I have the RVND 7720, great tool but wish I had bought the Garmin dezel. Not happy with the freeway exit graphics. My Tom tom has great graphics but not RV specific.

My vote's for the Garmin dezl 760 - it's the trucker's unit, but also has RV profiles (Height, weight, length, etc.) 7" screen makes it big enough to see in a big RV cockpit. Might have to load some campground POI files - but all the fuel stops are there. If you have a smart phone, there's a free Garmin APP that will link to the unit for realtime weather, gas prices, road info, etc. And the free Garmin Base Camp software lets you build trips on a laptop and load them into the GPS (my preference). As with any routing aid, it's probably not perfect, but so far haven't found any flaws.
