There is an electronic battery monitor that is ideal for serious dry camping. Measures the draw and current voltage of your battery. I think its called a Trimetric??? Many members here and on other forums had suggested it to me, but the shunted wiring was complex. Having the wiring done or offering it as an option would be awesome.
