:usaOWWWWWWWWWWWWWWWWWWWWUCH!!!!!!!!!!!!!!!!!!!!!!!!!!! Just tried your buddy's advise. (just kidding not really) My Macks are not so bad that way for noise. Had a GMC 9500 series a long time ago with a 6-71 Detroit and 13 speed in it. Drove it like I hated it and it ran fine. What kind of toy is on the trailer there?
