I was thinking about this the other day. They say that the average American drives 12,000 miles per year. I have had my 2005 yukon xl for just over a year and have put 21,000 miles on it. That is basically taking my son back and forth to school, driving myself to school, and driving around town doing things like grocery shopping. . We don't use the truck very often for road trips because of my wife's new van. So how many miles do you put on your truck in a year?
