ABOUT ARNOLD’S DIESEL REPAIR.
Arnold’s Diesel Repair LLC started in January 2026 because Trent Arnold and Vince Serwe have always liked working on just about anything, especially diesel trucks and equipment. In the first months of business, the company had already written more than 50 repair invoices covering all kinds of vehicles and machinery.
They keep investing in new tools and equipment so they can take on more work, diagnose problems better and help customers get back to work faster. Their rates are built to stay competitive, they’ll work on just about anything, and if there’s a problem with their work, they’ll make it right.
