    I'm glad I worked for a company that knows what it's doing. Any trainer asleep. While his trainee is behind the wheel. Would be fired.

    But at least it explains why you don't have the knowledge.

    My first trucking company is a company that is known for hiring rookies out of truck driving school. 90% of these students transfer to another trucking company within a year, so the company does not have a large incentive to train these students adequately.

    If these trucking companies gave some kind of incentive to stick around after school, they wouldn’t have such a turn over rate.

    If you could get a better deal after training and school with another company, would you stick around?

    Depends on how much better the deal was at another trucking company. I stuck around to be a trainer. It ruined my health. Now I have high blood pressure and ulcers, but I made good bank.

    The topping out of the suspension does not allow for what to articulate? I don't think that "Low traction" in that sentence refers to the traction between the tires and the ground. What does the topping out of the suspension result in low traction in?

    Topping out the suspension basically means all 4 corners of your drives are in the same plane (no articulation) . Unless you're on perfectly flat pavement, one corner will have significantly less weight on it than the others (and therefore much less tire to ground traction,) and will spin quite easily.

    I have an overlift system on my carhauler, and I usually lock the power divider at the same time I overlift, especially if I'm pulling out into traffic and will be getting into the throttle. For the exact same reason, with the suspension near the top of its travel, it's easy for one corner to top out and lose full contact with the ground.

    The TC light stays on when I am 20 feet or so from the trailer. When I am 20 feet from the trailer, the truck still moves extremely slowly.

    Because your rear axle is mostly off the ground.

    Next time you drop a 40k plus load, put the landing gear down until it just touches the ground, then pull out and stop as soon as the 5th wheel clears the trailer. If you get out of yhe truck quickly you will be able to spin the rear tire freely. Over the next minute you can watch the tractor suspension deflate and the 5th wheel lower in relation to the trailer.

    As a side note, if the traction control is engaging on dry pavement, it's a sign you should stop and let the air bags settle. You are risking differential damage by trying to force it through.

    So for your experiment that i can conduct when i am dropping a 40k+ load, i need to lower the landing gear until it just touches the ground and pull out from under the trailer WITHOUT DROPPING THE AIR BAGS; correct?
