Do you like your truck? Reason asking was the last time I read that a guy had a problem with a 2002 truck and when he came back to report how he fixed it he said he fixed it by trading it in on a 2009

No hating, We understand. Once you get that money maybe you can upgrade to somethingwith less miles. Buying a vehicle with such high miles always is a risk of problematic issues shortly after, but respect for you buying your truck and maintaining it.
