I should take a pic of a possible location. The bathroom sink cabinet has a panel to access the back of the fridge. Thought about building a little box and have the batteries vent with the fridge.
Trailer is on shore power while parked at home. Seems like the batteries get hit with 14.4v every morning and thats not needed since my converter is powering the trailer? Another idea is to store the batteries in the garage. Install them before a camping trip.
Probably a waste of time? $200 every 5 years is not so bad. The current batteries only lasted about 2 years. Fully charged my water pump is enough to trigger the low voltage alarm.
