About the Magazine
The August 2026 issue of Diesel World is packed with the builds, upgrades, and stories that keep diesel enthusiasts turning pages. On the cover, Road Dog showcases the Matkins family Power Wagon, a truck that perfectly blends capability, character, and old-school diesel attitude. Inside, you'll find Knowledge Is Power, a thoughtfully built OBS F-350 that proves careful planning always pays off, along with Heavyweight Hauler, a custom Chevy 5500 that redefines what a tow rig can be. The issue also takes a closer look at Raymond’s Wrecker, an International tow pig being brought back to life, and explores the fascinating idea of a consumer CAT pickup in Caterpillar Goes Consumer.
Beyond the feature trucks, readers can follow along as the Diesel World editorial build dives deeper into its 6.7 Cummins transformation and learn the hard lessons that come with owning a C4500. Tech coverage is loaded with practical upgrades, including Duramax torsion bar support improvements, airflow and engine bay enhancements for the L5P, and a full HSP makeover on a 2025 Denali Ultimate. Add coverage from the Diesels of New York season opener, fresh product highlights, and real-world diesel knowledge throughout, and this issue delivers the perfect mix of inspiration, tech, and heavy-duty horsepower for diesel fans of every kind.
