Diesel Tech Q&A

Originally Published in Trailer Life Magazine

To complement Trailer Life’s long-running RV Clinic column, we’ve launched an online technical question-and-answer section devoted to diesel tow vehicles.

Topics cover all aspects of diesel vehicles from engines to transmissions, gearing to fuel economy and tires to turbos. Each month Bruce W. Smith responds to one question in depth, and readers’ comments add to the conversation.
