Being hopeless after trying many times pressing pedal, then i saw the 4x4 handle down and start to give it a try, it was awesome! with only just one pressing pedal the tire go up smoothly just like it doesn't plunge at all!
Of course that wasn't the true power of 4x4 if compare with the offroader but personally, safety feeling while driving in unpredictable situation is enough to decide 4x4 jeep as my trusty companion. Then my first 4x4 jeep was Trooper diesel, at that time it was the only 4x4 jeep that match my budget.

This is not my car but the same model
