@hdmike2500 hahahaha your a dipshit. GM don't own cat. And peterbilt don't run cat. Cat engines aren't in any new trucks cause they couldn't meet emmisions. Ford took a loan and paid it right back off. Ford's makin hella profit this year.
@crakerjack3 yeah, only thing to worry about is smoke in eyes and the truck using up all the oxygen. haha, they are perfectly safe though. (I bett they smelled bad afterwards! haha)
