I made the access plate from a spring loaded outside outlet cover and just cut a notch and added some foam insulation to accommodate the cord with the lid closed. I had a much bigger cord drop , but I want to leave the space open in case I ever decide to add that 4th battery.




I store my Mr. Buddy heater and the electric heater under the seat, so I will need to move some stuff around to drop the cord when needed.

The outlet on the front of the seat is where I plug in the space heater when I use it. It is central and I can sit it out of the aisle way at night just under the dinette.
