Hi everyone, just purchased my first RV (5er). I plan on dry camping 90% and was surprise to notice how fast my batt charge drops after i disconnect shore line, all with no power turned on(about 20hrs...
if you don't keep the trailer plugged in and don't have a battery disconnect switch and only one battery, the parasitic power drains can empty a battery in just a few days. that's why many of us install a disconnect switch if we don't keep the trailer plugged in.
i have two 12v deep cycle batteries since i dry camp almost all the time. i can use the disconnect switch in December, for storage, and go back out in April, and the batteries have barely lost any charge.
