it's true tho', I found one place that said in the 19th century the average height of US military [good records] was only 5'7", we have gotten some bigger - GM paid a bit of attention to making things that fit the 'average' working man building these trucks, but note that the AD's have roomier cabs than the decos and the Task Force series is roomier yet .... one of the things I like about driving old trucks is the thoughts of the guys back then pushing them across country day in and day out
