Charge a truck battery through the trailer/truck plug
The wife and I are camping this weekend up in the San Bernadino mountains and this afternoon we were going to head into town only to find the truck battery is dead. We aren't leaving until Monday morning and I am wondering if it is possible to charge the truck batteries if I keep the trailer and truck hooked up through the bumper plug?
Currently the trailer is plugged in the camp grid (30 amp) and the truck is a Ram 2500 diesel with dual batteries. Plan B is to call AAA on Monday.
