I have the RV 770 LMT-S and love it. Replaced a Rand McNally RV gps that was terrible. In my experience the Garmin does a good job of routing and if you use the phone app the traffic and weather updates have been spot on. I like the setup for inputting the specs on the trailer and have found it very intuitive. Purchased mine on a site that sells refurbished units with full warranty for about 1/2 the price.
