Have any of you installed a battery monitor on your Aliner? Or small camper? Do you use a surge protector when plugging in your camper? I have a 2016 Aliner Classic and have an AGM marine battery. Use a 80 w solar panel about half the time. Not having problems but trying to avoid them. Since I added the larger more powerful battery I don’t have issues with enough energy over night. The battery that came with it couldn’t get us through the night. Using gas for fridge. Thinking a monitor would help me see where the battery is at so I don’t run out.
