Very interesting thread... I'm planning to keep the truck forever, so the extending the truck is an option and the $10K-$15K is cheap compared to getting a new truck and not knowing what is going to happen to it. My plan is around 10 years or so from now, I'll look into getting it extended and replace any body parts that are starting to rust out from the 4 billion tons of salt they put on the roads here in Omaha. Of course from that time, I'll have to get a new house with a bigger garage to house it... good grief, this truck is going to drive me into the poor house yet.
