These are the service manuals for you vehicle...usually a 3 volume set and contain the exact procedures used to repair each component in your truck.
Forget the chiltons, forget the haynes they are for general stuff, but if you want all go the above.
They are pricey $135 per set...but as I get new vehicles I get a set of manuals.....best investment I can make as 1-hour of labor is close to what these manuals cost......
