Have you tried switching over as many lights as possible to LEDs?
Switching to LEDs saves me 4 amps with the running lights on and 12 amps with running lights on and brake lights on. Also saves 4 amps with the turn signal.
Switching to LEDs saved me from having to switch to a larger alternator.
My problem was my battery would drain when driving the suburban during hot summer nights when I had head lights on, radiator cooling fans running and sitting at a stop.
It was bad enough to where I would turn the head lights off while stopped.
