The average life span of your truck will solely depend on how well you maintain your vehicle. My Tacoma is ten years old and has 230,000 miles on it. I have never missed a FACTORY RECOMENDED SERVICE on it and have not had to put it in the shop for any-thing other than a starter. So to answer your question simply, it will only last for as long as you care to take care of it. There is no set amount of reliability time span on any vehicle no matter the make or model. Love it like a child they're great trucks period.
