I'd like to buy a high quality repair manual. All the typical ones at the parts stores are crap. Most stuff I find in here or on Youtube, but would like to have a reference that doesn't need internet connection.

 

Since you didn't list what year truck you have it is difficult to be specific. There are two sources I've use over the years to get the full Ford truck shop or repair manual. Both are easiest to order online. Check on eBay -- there are both the printed and DVD versions available from 2004 thru 2014. The second source is HelmInc.com, the OEM supplier of Ford manuals. The printed versions are the full three volume manual that covers every aspect of diagnosing and repairing F150 trucks. (I've never used the dvd versions so I can't comment on them.) These manuals are pricey -- some versions running up to $160 new. On eBay it is sometime possible to find used versions for less money. Having used these manuals for over 15 years on various modes of
150 they far and away superior to any of the aftermarket manuals.
Hope this is some help
