So I am considering something that may seem drastic in terms of fixing up a van. But I am very interested in making my van as self sustainable as possible for my next month/two month trip. I want to take my mid driver side window out and replace it with a 3/4 piece of plywood. With that I will have an ac/heater hooked to an external battery powered by high wattage inverter. I will seal and paint the wood as well as I possibly can.
My question is do you guys think its worth it, has it been done, any problems with a ac unit sticking out the side of a van??
