Got my 5000 BTU AC unit and a little 700watt microwave setup today. I bought a shelf unit and tied some nylon rope to suspend the microwave under one of the wings. Out of the weather, easy to get to and uses otherwise useless space. I set the AC up very similarly. The wings are 13" above the floor of the trailer, just the exact height of a small window banger. Cut a hole in the tent flooring material, setup velcro around the perimeter as well as the AC unit, fit perfect!
Now I am reading to go camping. I realize the AC will not run on the battery setup, but the microwave will. This is for campground camping.
