This is always a good plan. Training is primarily safety-focused, showing you the correct way to use your car without doing any damage to it, or yourself. The theoretical knowledge is also worth it. An instructor will explain the various 4WD systems (AWD, part-time 4WD, full-time 4WD) and when to use each. In addition to all of this, a proper training course will also focus on recovery and basic maintenance techniques. Multiple accessories can do some serious bodily harm, and before you take on the great outdoors, you need to know how to use them properly.
