I have both...neither are very comprehensive...if you want the best references, search ebay for the light duty truck manuals for your truck's year on ebay.
I like to have a physical copy in my hand. It is easier for me to grasp! "Working" copies of the Ford manuals can be had on Ebay for relatively cheap. The Ford manuals are far and away more comprehensive, with "less" mistakes. I have less in quotes because there are some mistakes in the Ford manuals.
