I personally wouldn't have a truck without it, but I live in CO. We did a trip last March and watched the weather like a hawk and there wasn't any snow in the forecast. Last day of the trip we woke up to an inch of snow in central WY. It snowed for about 4 hrs and our trip on I-80 was scary! We switched to 4wd when we left the campground and drove less the 5mph for the next 150 miles. Semis were spinning their tires and stopping, we saw a bumper pull trailer on it's side and countless cars and trucks in the ditch. We never spun our wheels or felt out of control the whole dive. So if you travel where it snows, don't leave home without it!
