I've read through archives on this and learned a lot but can't quite resolve my question.
I'm having battery problems. I was be plugged in with the monitor indicating the batteries were full. Drove 1.5 hours with the fridge set to battery power and arrived with the monitor saying they were empty.
I bought this 2016 camper used and don't know how well the batteries were cared for (I bought it from second owners who'd had it a year and only used it, once so batteries could have just sat there unattended). My first thought was batteries are bad and not holding a charge. Now I know from the forum that there is also a charger that could be bad. Any thoughts on how to tell which is the problem?
Thanks for advice. :)
