If you are thinking about a class 8 truck and are not quite sure about it's systems & characteristics or driving differences, I have a book to recommend: Bumper To Bumper, The Complete Guide to Tractor-Trailer Operations by Mike Byrnes and Associates, 2025 North Third Street, Suite 155, Phoenix, Az. This is a textbook used for training truck driver students. The parts dealing with tractor systems, maintenance, pretrip inspections, and driving are very informative.
