Keeping a good thought for the next door opening for you Chy
Don't know if it interests you, but there is a dire shortage of techs in the heavy truck industry. Direct diesel / heavy experience is often not a hiring issue, especially with your background. The engine specific dealerships often have the most modern / clean / best equipped shops. On another note, I have a number of nationwide contacts within the tank truck industry from many years of active participation within an industry trade group, if that helps. Might be one of them needs a good man to run the place.
Just a thought...
