Since I have a work truck that does more than move my butt around I was already planning on installing Marine starting and deep cycle batteries at some point (stock configuration is for 2 large batteries). I have a small 700 watt power inverter installed now and will likely get a much larger pure sine wave installed in the near future for running tools with out a generator, also have a flood light and will likely install a spot light and i am ready to install a 50 amp 12v air compressor when I have the time. I have also converted over to electric fans, electric cooling pump and electric fuel pumps.
This is why I have to keep an alternator for night time and PTO use.
I searched around and found:
"Electricly unhooking" the alternator seemed to net about a 5% gain.
Deleting or unhooking the belt seemed to be the real money maker, +10%MPG.
Just running off battery power alone isn't that appealing since each large marine starting battery I have been eyeing will run nearly $180 each.
I had already been considering a small solar panel to keep the batteries topped off in winter, now I am thinking about scaling that up.
