Solution is solved very easy to determine model year, just look at the VIN plate ( for the coach) and read left to right, it's a 17 digit vin# that has all the information, now vin code POSITION 10 is the model year, if it is a 2009 it will have a "9" in the 10th position if it is a 2010 it will have a "A" in the 10th position. Now that was easy huh?
