I was in shop for 3 months before I hit the road.Was a line lead in a factory before that for 3 years.Part maint part setup part get your butt chewed.I was told acceptable amount of time for pm service.Bill what it took on repairs if you get upsidedown on a lift call in and see what boss wants you to do.I always say let your work speak for you.If you do good work then it shows if you half do then it shows.First year on the road I was afraid of anything with a plug.Ie electric lifts.I was told so much hog wash it wasnt funny,These men have moved on I for one am glad.They wanted to be the only tech to be able to fix them.Our card sales droped after they left.Every thing had to be a card.A lot of what they did was parts swaping swap till it works.I want to know why.I also dont mind sharing information,I have enough to do in a days time without running all over. Road time isnt that much fun for me.I do love a truck that gives me fits it makes you learn.The only problem I have is how much do you learn when your told how v/s figure it out yourself.Hard knocks has taught me more than easy going,in life and in repair.And I still get a kick out of fixing a truck.When thats gone I probably will be to.
