The best thing to learn is driving by the seat of your pants. Feel what the truck is doing with your butt. I know it sounds funny but it will save ya.
When you are driving your seat will tell you what is happening under your tires before anything. If you get a soft feeling, like its getting mushy, stop.You can also tell when your truck is starting to slide one side to another or the front or back is starting to sink both are pre cursers to getting buried.
Put your truck in 4 LO. Get into your lowest gear and use as little gas as possible to get the truck moving. Do not make any sudden moves with the wheel or the gas until you get the feel of what is happening.

have fun!!!!!!!!!!!!!!
