If you REALLY want to be a power miser, check the voltage of your batteries over their full operating range, if they are less than 12v at any point during use, then make a DC-to-lower-voltage-DC converter and add some really heavy duty spike protection for during engine startup. Lowering DC voltage is very energy efficient, and the lowering circuitry will make sure no steady higher voltage will have an effect. Hot wire that straight into an old battery case with the actual battery cells removed. (You can't get better than that without breaking open the computer. And even doing that would have no benefit unless you are using golf cart batteries for your house bank and tap 6v off one of the batteries, and then feed that into select spots within your computer.)
I could say more about this method of using the battery case, or even design something that would work if there's enough interest.
For the money I think you'd be better off swapping all yor interior lights for LEDs. There are great threads here on the best kind to get - search for the comparison testing by Mainesail.
Great minds discuss ideas;
Average minds discuss events;
Small minds discuss people.
The best minds discuss sailing (and a little bit of politics). I don't know why. It's a mystery!
