Hugh and Tammy Pennington like to drive. They like to drive a LOT. The owners of a 2006 Chevy Silverado have eclipsed the million mile mark on their truck, and drove it back to the place that built it for a celebration.

 

The Penningtons bought the 2006 Chevrolet Silverado 3500 HD crew-cab with a Duramax Diesel and Allison transmission in Georgia, and their first trip in it was a vacation back to Michigan. What makes their million mile feat even more amazing is that a majority of those miles were spent hauling fifth wheels and trailers.

If you have done the math, a million miles in six years is nearly 500 a day. Every day. The Penningtons live in western Michigan and were driving through Chicago when they hit the million milestone. The odometer went haywire and read "error" and required them to have it serviced so they could continue driving it.

The secret to their truck's longevity? Regular maintenance. They change the oil every 3 to 4 thousand miles. They go through a set of tires twice a year. They needed some repair on the transmission at around 850,000 miles, but that was the only time they had to put money into the vehicle outside of regular maintenance.

The couple received gifts from the people who work at the Flint Assembly plant on Van Slyke, but the people at the plant got to see an example of their craftsmanship and quality.

The Penningtons plan to keep driving their truck. Perhaps they'll be back when they hit two million miles.
