Mine was replaced at 223,000 miles (mostly towing a 14,500 lb. rv) in my 99 with 6-speed. Actually the clutch was fine but my throwout bearing was out. Since they needed to drop the clutch to replace the throwout bearing, they replaced the clutch. The shop owner commented that if he had not known that I pulled a large rv, he would have left the old clutch in the truck as it showed little wear. I have no performance enhancing stuff and being an old farm boy, was taught early to keep my foot off the clutch. When backing and maneuvering my rv, I usually engage the 4wd in order to slow things down and avoid riding the clutch.
