I purchased the RV770 when they first came out in March 2017. At first there was a problem with it working with BaseCamp but they quickly released a software update and all was good. I have had about 6 Garmin units over the years and the RV770 is the best highway unit so far. The screen is clear and the touch screen operation is crisp. The maps still have a few issues but they will never be perfect. You might need to adjust the settings for your RV size and weight and do not select the propane option in order to get dependable routing. I always verify my routes with BaseCamp and Google Earth. The LiveTrack feature is cool, I entertained a few of my friends with the ability for them to follow along on my route every day I traveled.
