I have kept up with all the regular maintenance with oil changes and tire rotates every 5k miles. Truck is in really good shape. Only problem I have ever had with this truck is the starter went bad this past Spring and it was replaced. Always stored in a heated garage. Love this truck and planned to keep it many more years but an opportunity came up with another one that I couldn't pass on.
