Thanks to all who responded.? I have a solar panel permanently mounted on my Aliner which helps charge the battery while towing and have never had any problems draining the battery with the fridge running on 12 volts.? My concern is that sometimes when I am camping in the deep woods I do not receive enough sun on my solar panel to charge the battery so when I leave the campsite my agm battery is discharged.? If the same thing happened with a lithium battery, I was concerned that this might cause a problem with my alternator while towing home.
