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 would note that AFAIK, within the main, household copper wire is commonly attached to aluminum lugs harboring steel screws...".
That appears to be true for the neutral bus bar.
The ground buss bar is steel/steel.
Are we talking metallurgical compatibility, conductivity, or maybe something else - I’m somehow missing your point?... I’m of the ‘KISS’ persuasion - I’ve often seen aluminum wire and copper wire and steel components co-mingled within the same Main...BTW, your aluminum chassis is a far better conductor than steel, yet steel is commonly employed as an effective ground return in all vehicles...You’ll be fine so long asyou apply a small dose of De-Ox...
