Annual Trailer Maintenance & Safety Checks – Minnesota

At All Mac Inc., we provide certified MN DOT trailer inspections and detailed annual maintenance checks. Our goal is to keep your trailer compliant, road-ready, and safe. Whether you manage one trailer or a full fleet, we’ll make sure your equipment meets the standards.

If we find minor issues—like a broken light or loose wire—we’ll fix them during the inspection. For bigger problems, like worn-out brakes or damaged tires, we’ll call you for approval before doing any work. After an accident, we can also give your insurance company a detailed repair estimate.


Trusted Maintenance Since 2003

We’ve built our reputation by doing only the work that’s truly needed—and nothing more. Most of our new clients come from referrals, and our long-time customers keep coming back.


What’s Included in a Maintenance (Safety) Check:

Our checklist covers every major system:

  • Tires and Brakes
  • Floor and Undercarriage
  • Lights and Electrical
  • Roof and Ventilation
  • Breakaway System and Plug
  • Safety Chains and Hitch

We recommend that every trailer gets a full maintenance check at least once a year—depending on how often and where it’s used.
