My main concern was to be able to charge cell phones, GPS units and In Reach or SPOT locator beacons. I was wanting to wire the unit into the trailer since it also has a USB charging port I would have a couple options for charging my stuff.
Right now I do my charging in the truck but the 12 volt and 120 volt plugs only work with the key on, only plug that will charge while the truck is off is one USB port. Not sure which knuckle head decided that we don't need to be able to charge stuff without the key on.
