keep in mind the nature of the beast. It is not a house. Thinner walls, less insulation, high percentage of glass to wall surface, lots of heat gain, especially the windshield. You can shade the sides some with window awnings and porch awning, but the roof, short of tree shade is in constant solar exposure. Plus, where your a/c ducts are, in the ceiling foam insulation, creates hot spots because of the reduction in insulation. But by maximizing shade, running the a/c fan all the time, you can actually do a pretty good job of keeping the inside at least 15 degrees cooler than the outside. However, when it gets above 100 outside, its going to a loosing battle, just not enough wall and roof insulation. So have some inside fans to keep the air moving.
