Got the Garmin 770LMT-S 2 weeks ago and I have to say its has been a great purchase. A lot of your typical GPS functions remain the same only its super fast and the screen is huge. There are plenty of other very cool functions to help with RV travels. Too many to list. As other people have said don't rely on a GPS solely and have a good map to use because as we know technology is not foolproof. I know $400 is a lot of money but for me it was worth it.
