[MrE]

I used Google maps on my smart phone to get from Austin Texas to Boise Idaho. I learned to ignore some of the directions, there were numerous times where it was alerting me to an upcoming turn that common sense told me not to follow directions. There were also the times where I would have felt comfortable in a car, but not in a 40' 102" wide motor home. From what I've seen so far, I'm leaning towards the Garmin Dezl where I can let the GPS unit know that I'm not in a 4x4 jeep.
