I'm a big fan of Diesel Power too. It's great timing for an all diesel mag obviously as the popularity of these motors has surged beyond belief the last couple of years. The mag is great, so great that I haven't been able to locate the second issue if my life depended on it.
And that sucks because I've heard from others that the second one was pro-powerstroke with most of the magazine devoted to us ford guys....grrrr!
