The First thing to find out is, Is the truck charging the camper battery. Sounds like it might not be. On some GM trucks you have to put in a fuse before power will get to the camper to charge the battery while you are getting to the destination. You will need a good voltmeter to check this. After running the truck for a while camper battery should read around 14 volts while the truck is running.
