I also have a Garmin760LMT with the Backup Camera. I have only used it on one trip and it tried to send me the wrong direction on I10 in the California Desert. I knew I wanted to go west so I ignored the instructions to turn right that would have taken me East. The backup Camera is powered with the License light so that I can see the boat or toad when I am underway. It is also a perfect addition to the stock backup camera that is more to keep you from hitting things rather than truly backing up. After you get the Garmin Backup Camera dialed in, you have lines that represent RV clearance.
Good Luck and Safe Travels.
