I too am very interested in diesel technology. I love to impress my bosses with getting inside scoop information on stuff before it beomes mainstream. (I am a firefghter and de facto mechanic, and the training budget is low, so I have to do it myself.)
Besides, all DRN'ers should have diesel trucks. It is the environmentally, socially and economically correct thing to do. Despite what the misguided greenies say, diesel pollutes less in the total picture due to engines and vehicles lasting longer, necessitating less engergy spent in new vehicle manufacture, and with biodiesel on the horizon and here today, we can cut imports of foreign oil, and besides, diesels get better economy.
