How many tractors?
We have 175 drivers and our company fleet has historically been 100% International tractors.  However, we have recently purchased a few 2009 Peterbilt tractors to test.  We replace all tractors on a 4-year rotation and currently run upgraded 2006 and 2007 model years.

What engine and transmission are used?
Our tractors are equipped with ISX Cummins and we run 10 speed Ultrashift automated transmissions.

How many trailers?
We maintain a 2:1 trailer to tractor ratio - all are 53' air-ride equipped.  Our fleet makeup is three-fourths dry van (plate trailer with wood floor) and one-fourth reefers.
