For mine, there were not enough photos of the various models on offer, and only a scant history afforded to the different assembly plants...their opening and closing dates, and a list of all the current plant locations would be helpful.
There are photos of kenworths which are missing their model description. For example; the Australian Kenworth road train picture. Most readers would not know the model number, nor the years in which it was produced.
I would have thought that the W900 A extended hood model deserved a chapter of its own, with all the various big engine options listed and the fact that they are so keenly sought after today. See if you can spot one picture or mention of one in the book. While you are at it, look for a W900B as well.
As much as the T600 series may have revolutionised truck design, Canada and Australia produced their own models and these countries are largely glossed over.
If I was the President of Kenworth, I would have sent the author back to do the job properly. Much attention was focussed on the recent and current model line ups at the cost of the older ( and dare I say) more popular models. While it is easy to get new truck brochures showing interiors etc, it is the older models which are more difficult to obtain details on and it is these which hold moch appeal for fans.
This book took the easy route, and as one reviewer has pointed out, some of the writing reads like a truck brochure...thinly disguised advertising, and that is becasue some of the material is from the truck brochures.
So, if you are into Kenworth by all means buy this book. Just do not expect everything to be there. Some day someone will be passionate and thorough enough to produce a book on Kenworth that rivals those written about Peterbilt and Mack.
If you want to learn more about Kenworth, and in particular Paccar, hunt down a copy of "Paccar The Pursuit Of Quality" by Alex Groner.
