Any 'old truckers ' out there??

You guys might be right. I watched it again for sh&%s and giggles and I think its real time sound. There are a bunch of scenes when the truck is running and I am not quite shure that is dubbed in. Anyhow the part of that movie that almost brings me to tears from laughing is the very end when 'Dirty Lyle" is cracking up at the so called funeral for The Duck. Yeah, its a great movie. Just watched another truck flick last night and as a bonus there is a Mopar in it. "Duel" with Dennis Weaver in a Red 71 Valiant being chased all over and stalked by a very old Diamond Reo. This was Steven Speilbergs first movie and it is crazy. I would love to have that truck to restore!!
