I have a Nuvi 360 with all the North American maps. It's a GREAT unit, lots of locations/stops, quick redirect when necessary, and having the option of staying on truck routes is a bonus with the RV. The only thing I don't like, as with all units, is that they don't account for low bridges. Sorry, but 15' doesn't classify as a low bridge (as per a TomTom unit I tested). If Garmin could master the art of low bridge truck mapping, they'd have a repeat customer! Providing they list clearances that are under 13.5' only.
