Now that the weather and roads are crappy, I have been extremely happy with the traction control on my FX4. Bought my truck at the tail end of winter early this year and didn't get a chance to give it a good shakedown. The past two weeks have brought rain and then sub zero temps. With the traction control on, a guy would really have to work at it to spin out the rear end in 2WD, I haven't been able to do it yet! This truck has come a long way from the 2002 that I had last winter. Hats off to a great product!
