james j neiweem Posted August 7, 2019 Share Posted August 7, 2019 In looking through the Mack body builders PDF (I may be wrong) but it seems that every Mack conventional is 116" BBC. If that's true no wonder they have a 5% market share. One size fits all. I read in a trucking pub (HDT I think) that back in 2010 a Mack corporate spokesman said with the 116 BBC we may have some problems filling customer specs. Gee ya think.

bbigrig Posted August 9, 2019 Share Posted August 9, 2019 It was 112" until they added the 4" to the cab for the MP engine doghouse and new interior for 2006/7 Quote Link to comment https://www.bigmacktrucks.com/topic/58490-bbc/#findComment-429737 Share on other sites More sharing options...
