First camping trip, and noticed that the frig will work on AC, but as soon as i pull the AC the frig goes out / powers down completely, and won’t switch to LP. With AC already connected, i can switch to LP, no problem, and back to AC. Does the frig stay on, when only using battery, or do i have to plug the camper into AC before switching it to LP? My last camper automatically switch even on battery. I am a bit confused on this.

Thanks
