For those who want an extra source for their truck info, you might check out this online site, AlldataDIY. While it may not match the $100+ cost for a set of factory books (It costs 24. 95/yr, up from $19. 95 recently), it includes a very comprehensive list of Technical Service Bulletins and Recall Notices, which you can find elsewhere only if you really look. It also has some good general info like safety procedures and troubleshooting hints. The info is updated every quarter, and is formatted to your specific Make/Model/Yr. This isn't a sales pitch (nothing in it for my bank balance), I have a subscription for two of my vehicles and it's been very handy for quick reference. I think that you can also subscribe through the AutoZone website.
