Even if this has nothing to do with the great systems you delt with and they are not applicable with little trucks?
I've worked at franchised Ford dealers since, we'll probably before you were born. In management for 20 of those years. Since the abomination of the 6.0, (introduced early 2000's) Ford techs had no choice but to be certified heavily on it and every Diesel engine since. Tune up techs took a backseat in pay and hourly rate for the first time in forever, in my experience. As irrelevant as this may seem, to you, we are talking up to $12 an hour more. For the last 12 or so years. Unless all Ford diesel techs are certified, (more class time work then any dealership techs) they can't touch warranty work. But that also applies for all Ford techs. They also need helpers to efficiently lighten their load. Each helper works their way up and spends generally 3 and up years at the same dealership as the diesel techs. (From my last 2 dealerships, 16 years combined.) I've seen helpers from lube, brake and front end and even heavy line techs, (gas engines) jump at the chance to to be selected over time to become a helper. And helpers have the fasted turnover rate. Seen plenty of techs come on as helpers, and 2-3 weeks later, they are either packing their bags or pleading their case to go back to their trained department. Many times already filled. Finding a good diesel tech is the hardest of any other tech in the business since the 6.0 came out. Beyond crap. But a hell of a money maker for dealership personnel.
Oh, the sharp ones don't stay around? Current 3 techs have stayed around, 27,14 and 9 years. last dealership I worked, somewhere around 12 and 8.
So for you to say they don't have a clue? Maybe with the systems you deal with. They have far more knowledge then both you or I. I'm sure you're rebuttal will be grand! Such as, you only work on big stuff, weren't talking about factory dealership personnel. You know, garbage, argue, and being the foremost expert in all that's clean air.
I'm sure this tl;dr. Has zero to do with the rants that will soon follow. You know, (non applicable) such as factory techs using some miracle system you worked with. But I'm sure the great systems you developed also have zero to do with itty bitty trucks.......... Just don't recall the thousands of words excluding them.
Oh, if you want a rebuttal from I, or ignore, could care less. Won't happen. Maybe I'm all wrong. But as long as you are right it's all good!
Peace.
