I was disappointed with the gas mileage and the 4WD until on a trip into the desert the pavement had run out. It had been raining for two days and the road was a mass of mud and water. I put it into 4WD low and powered through, no problems. We went about a mile until we reached a road and although hairy it was fun and we made it without a problem. This truck is a billy goat and I would not hesitate to take it 4 wheeling any time.
