Fraid I don't use manuals much--seem to figure most of it out w/o books--always have. When I was a kid had a chilton's manual long since gone--electrical is tuffest for me--not much interest in electricity but my old man was a EE so he answers most questions.
When I do get bored with truck or tired of chores do read some--principally Wallace Stegner, Cormac McCarthy, a little McMurtry--stuff like that.
