Am I Supposed to See 12V at the Tail Lights?
Re our Coachmen Freedom Express 192RBS: I have a verified measurement of only 10.39V at my left rear tail light. I am producing 13.9V from my 7-pin connector on our Ridgeline at the tail light term...

Back from my appointment and have set up my meter to test this circuit again.
Status: (1) Ridgeline and 192RBS connected via 7-pin bargman; (2) truck and trailer NOT hitched; (3) shore power disconnected; (4) running lights powered up at truck's dashboard.
Picture of exposed wiring:
Note: Black wire is "hot;" Green wire is "negative;" White wire is ground
Applying my meter's probes to the Black "hot" and White "ground" wires I receive a measurement of 11.42V. (Edit): I just received a call from the tech at our Forest River dealer, and he suggested seeking a ground measurement at a point on the frame. Doing so yielded slight improvement at 11.51V.
My ultimate question is: will this amount of voltage be sufficient to charge my Swift Hitch SH04 camera? It mounts nicely on my rear bumper with its own magnetic base - augmented by two sheet metal screws to secure it for travel. I've used it a couple of times in this way and the image on either an iPhone or iPad is remarkably stable and clear (this is a wi-fi unit). The camera's internal battery is rated for 5 hours, but I would like to keep it charged underway for any extended trips. The best answer will come from the Swift Hitch people themselves, but when I discovered what I perceived to be a low voltage reading at those tail lights that started a whole new area of concern.
Final thoughts, anyone?
