12V wiring Aluminum Cargo Trailer conversion
Been searching for days and haven't found a clear answer on whether or not a 12V system should be grounded to the chassis of a 100% aluminum framed enclosed trailer. Am I better running negative wires...

I think most RV's have interior ground wires coming back to the electric panel. You could try reaching out to Jayco or any other manufacturer customer service and ask them how the interior lights are grounded.
