This was my dream truck, and it's in perfect condition. I bought it to tow a large sailboat on a gooseneck trailer, but I never did. I've driven it 10 miles to & from work, carried a few sheets of plywood for home projects and took two 4,000 mile vacations. But, it's never been a work truck. On the highway, it's surprisingly smooth, considering the heavy suspension and gets around 20 miles/gallon. I'm selling it so I might retire a couple of years earlier. Otherwise, I planned to keep it forever.
