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...

The NEGATIVE is not a corrosion issue
It is a GALVANIC ISSUE.
Never use any part of a non noble metal as part of an electrical circuit. The circuit must be totally isolated from both AC and DC electricity.
Load negatives back to a distribution block. Distribution blocks to a central bus bar which will connect to the trailer battery AND the wire to the tow vehicle plug. Being mechanically connected to the two vehicle influences nothing. But connect bo grounds to trailer chassis or frame.
