Every time I saw this thread pop up I kept reading/thinking/envisioning a turret gun being mounted on top of someone's truck (truck gun) and wondering who the hell's trying to do this,
and they probably live in Arizona..

I bypassed this thread so many times and today was the first time I clicked on it to find out wtf... Honestly thought somebody had a gun mounted on their truck. Sorry for the hijack, back to your regularly scheduled program.
