What Firm said. Don't do anything special. Use 4x4 sparingly. It helps that the truck guzzles gas when you're tooling around in 4x4, so that will motivate you to use it as little as possible, lol.
BTW, hot tip: You can fully disable traction/stability control. Press the VSC button once to disable traction control. Stability control will still be active though, which will kill any 'fun' you want to have. You need to long press (like 3 seconds) the VSC button AGAIN, to fully defeat stability control. BOOM. Now there are ZERO nannies.
Find a large empty, snowy parking lot, put it into 4HI, and let that V8 SING. The deeper the snow, the better. Have fun!
