We have a 2022 RAM 2500 pulling a 2023 Flagstaff TT that has a Furrion Observation camera installed by the dealer. When the Furrion monitor is plugged into the 12 v outlet on the dashboard, and out headlights are on, the monitor picture is perfect--but our truck display screen goes dark and no amount of adjustment helps. Furrion suggested we purchase an adaptor to plug into a USB port, but that hasn't helped. Unfortunately, there's no power source except in the front of the cab. Has anyone else had this problem? Suggestions welcome! (FYI--When our truck lights are off, both systems work fine.)
