I am planning my first real boondock trip for a few nights off and on when we head out west May-July next year. I want to test the drain on the batteries before I go to know where I stand in various lighting scenarios and monitor the total amp-hours used. While searching for a battery monitor to check my consumption I came across this on Amazon for less than $20. What do you regular boondockers use?
