Once on your own with newer trucks out there. You will have to expand you learning to include things like IMAX tire inflation system Wingman avoidance system Ride height stands and anti dock walking devices. Apu And many other devices
How many out there realize and wish they would have paid more attention in school or asked better questions? How about when they got hired and put with a trainer asked more or was taught more ? Even years down the roads there are things you will forget. And you have to learn what you didnt learn on your own at school of hard knocks.. would it be nice to have resources at your hands?
