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...

Your link sounds like a concern for corrosion which can become a problem. Good maintained grounding would do the job. 10 ga is likely over kill for the running lights ground especially for LED lights.
Are you going to use the TV to charge the trailer battery? Regardless I'd ground the 12V interior system including any incoming AC to the trailer.
Aluminum conductivity would not be a concern for me but long term corrosion can be a issue.
Trailer house batteries will be charged by solar and a IOTA 45 converter when connected to AC via either a generator or when at home. Exactly what do you mean regarding a well maintained grouding? Cleaning were it grounds to the frame from the batteries frequently?
