Most trucking companies have really high turn over rates. I even heard one company bragging that they ONLY had 35% turn over a year. So, I just wouldn't bring up the whole I only wanna work 9 months thing and just work 9 months and quit. If the company you were working for was happy with you they would probably take you back anyway. Do you wanna work 9 months straight and take 3 months off or do you wanna take a month off every quarter? If the latter is the case you could probably find a nice fit in the oil fields hauling sand or whatever.
