48bigtrucks,
Your answer does make a lot of sense and I will ponder on that one. So, you are saying, they shipped most of the five's to the west coast and the three's to the east coast. You know, all of the trucks that I looked at (over a hundred) over half of them had heaters, in the Bakersfield area is does get to -32 degrees and I am sure most vehicle owners would want a heater, truck or car. So, on the west coast they had five windows and heaters... hmmm
