I don't have a picture of it, but years ago a company in Colorado Springs built a Suburban that had a GAU-17 in it. This is the gun the US had mounted on aircraft in Viet Nam, that would shoot 6000rds a minute(nickname was Puff the Magic Dragon). The company cam-ed it down to shoot only 3000 a minute though. It was built for security for some royalty in Saudi. I think either that or quad 50's mounted in my 1 ton would do the job nicely....
