Mack Superliner w/ Custom Bentz Sleeper

[@r1299]

Back in the day I used to drive a Mack superliner with a 475 Cummins twin turbo. It was bought out of Canada, it had a 300 inch wheelbase. We put a 18 ft dump on it with a wet kit. It had a 13 speed road ranger. In the winter time when you started that thing you couldn't see it for about 20 minutes. It ran good. It was supposedly a factory engine I've never heard of one since.
