Heavy truck sales really collapsed during the great recession, falling to a low of 180 thousand in May 2009, on a seasonally adjusted annual rate basis (SAAR). Then sales increased more than 2 1/2 times, and hit 479 thousand SAAR in June 2015.
Heavy truck sales declined again - mostly due to the weakness in the oil sector - and bottomed at 366 thousand SAAR in October 2016.
