The goal was to find shops that can handle the real-world demands of heavy-duty equipment in Tyler.

How to Pick the Right Heavy-Duty Repair Shop for You
Start by thinking about what kind of equipment you run and where you usually break down. If you're an owner-operator with a single truck, a shop like Accelerated Diesel that offers personalized, hands-on service might be your best bet. Fleet managers should look for shops with dedicated fleet programs, like Hex 6's Fleet Advantage, and ASE-certified technicians, like those at Josh Hawkins Automotive. If you're frequently on the road and need 24/7 coverage, a dispatch network like Road Rescue Network is essential. And if you value convenience and mobile service, Xpress Auto & Diesel can come to you. Always check reviews and ask about parts availability before committing.
Automate Your Fleet Maintenance Workflow
You can streamline your repair process by setting up a simple automation: when a driver reports a breakdown via a form or text, automatically log the issue in your fleet management software, send a notification to your preferred repair shop (like Hex 6 or Josh Hawkins Automotive), and trigger a follow-up reminder for post-repair inspection. This cuts down on phone tag and ensures nothing slips through the cracks.
