I had to take apart and re-assemble inside the locker. It's just large enough to pull my air conditioner. I have to "manage" the loads while using it or charging the AGM batteries when the get really low. I also have 350 watts of solar I really love. The new ones put out eben more power so they would be even smaller. I'm only on a weeks cruise using other club docks so I didn't install the second panel which hangs out the back.
