2020 Keystone Cougar 26RBS. After a 4hr trip home, low voltage prevented the slide from opening. The fridge was running during the trip. Plugged in and opened the slide. The next day I had the battery tested and it's fine. I verified that the truck charges the battery. Yesterday, with battery at 13.6, I unplugged. Fridge was running. This AM, 6.3 volts.
What direction do I need to head? Only the fridge and propane detector were running on the battery.
put your fridge on propane, and get new batteries. if you ran it down to 6V its toast. I am saying to put your fridge onto propane as when I looked up your model it saud propane/electric fridge so I am asuming you have a 2 or 3 way.
