If you tow with the truck, I would put in a SouthBend clutch. I just posted a thread yesterday, trying to figure out which model SB clutch to use. I'm going to go with the Con O. I don't plan to really mod out my truck. If you're not towing, keep it stock, if it's cheaper... . my Luk clutch is still going strong, after 120,000 miles... . I just believe in preventive maintenance.
