Just got my Garmin RV760LMT. So far I love it. Does exactly what I needed it for. Used to have the built in GPS in my F250 Lariat but the trim package on my new F350 does not have it. I have missed my back up camera the most and I bought the Garmin with the backup camera included. Will get it installed this weekend but I did temporarily get power to it and it connected to the GPS right way. I'm pleased with all the extras it has.
Edit:
Got my back up camera installed into my back up lights. I've also installed a wire and plug to one of the upfitter switches so I can plug it into that if I want to put the camera on the back of the trailer to monitor during trips. Just a simple matter of unplugging from back up lamps and plugging into upfitter system.
