By the way, in case you're all curious, I'm using one of my 3 drawer dressers as the box. I plan to make most of the top plexiglass, with a 4 inch "drawer" so to speak. So that when you look down on the top of the trailer, you'll see my amp, the subs, and some neon lights to show everything off inside. The trailer will have a flap lid at the front, with a nice sturdy lock and hinge. The whole trailer will be sealed, waterproofed, and sick!
