Interested in hearing from anyone with a 2018 diesel Prado that has fitted a dual battery system.

What did you fit re battery charging/isolation and are you happy with it?

Asking for my son who has been told the Prado alternator now means that a DC DC charger or simple solenoid must be used and that he can't use the Redarc unit out of his old (2003) petrol Prado.

Thanks in advance for any responses.
