DW is the assigned Navigator and Ultimate Cruise Director. We like MAPS!! Real, foldable, take 'em out and read em and plan ahead maps. My younger brother is a retired Nevada Highway Patrol trooper assigned to eastern Nevada literally in the middle of nowhere. He has lots of stories of folks stranded on dirt roads out of gas and no help in sight because they believed their GPS.
All I'm say'n is get what ever GPS looks good to you. Just don't forget to take a map along and don't give up on good common sense when following the electronic directions supplied by a voice programmed by some "snowflake" who probably hasn't traveled 50' from his parents basement couch
