I'd cut a whole in the bed and connect it to the cabin. Seal the top of the bed and then install 3 MTX Jackhammers. Have them facing into the cabin and use whatever room you have for the largest port possible //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif You would need about 9 amps to run that, but I bet you would hit 150 //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Very nice truck. My grandpa had one for years (older obviously) and it was a workhorse, never had a single problem with it. If I got a truck, I think I would get something similiar.
