I still use my old RV 760 LMT. The height, weight, length feature is nice, but note that when in RV mode, it won't take you through an uncharted zone. It will take you around, sometimes to a different state if necessary
Outside of that little flaw - I love the big screen, the loud voice, the lane change info at exits, and I like the campground searches that informs you of nearby campgrounds and types of hookups available, to name a few features.
PS - the rear camera feature sucks, don't get it.
