that ofcourse if you wheeled it.

Take a real close look at the pic where the amps are visable and you will see a custom made solid steel bracket coming off the rear factory tire mount bolt. I custom made this from 1/4" steel plate, 24 inches long, 1/2 " diameter bolts x 4 bolting it through the platform and into the MDF. Another similar plate from the front side factory spare tire mount into the box, and two huge L brackets from the floor up the sides of the platform. Inside the MDF box there is a complete frame made of 2 x 4's, around the top and bottom and front to back braces, which the platform is also bolted too with 3/8" bolts. This is as secure as the factory inside spare, I've done some very aggressive offroad driving and the box doesnt even squeak. Amps are mounted on special vibration pads 4 per amp to protect them, and of course an Optima mounted on its side in front, again a custom bracket I made that bolts the battery into the front battery enclosure. I started building stereo stuff and lowered cars back in the late 90's so I've already made the poor mounting mistakes and this isn't one of them. 50 - 60 hours in just the back of the truck, doesn't look all cool like fiberglass but I lost less than 1 cuft of storage space compared to the spare mounted inside. Like I said I like it.... :-)
