So I have had my new Pioneer at a storage facility in town since I bought it a few weeks ago. I've been down to the camper several times, slid the slide out in and out every time (that's so cool!), run the awning, the lights, etc. Once I put the house generator in the back of the truck and ran the camper off that, but otherwise it's been all battery. Which I've drained. I'm taking the kids upstate tomorrow, about an hour and a half drive. Will the battery charge while I'm plugged into the truck, and will it charge when I'm plugged into a shoreline? Should I plug the umbilical into the truck and leave it running every time I go down to the storage area to putz around in the camper?
