Building A Fleet Maintenance Program That Works
Light- & Medium-Duty
A guide to preventive maintenance intervals, cost tracking, and DOT compliance for Northern Colorado fleets, plus what Truck City handles when you're ready to schedule.
What should a fleet maintenance program in Greeley actually include?
A working fleet maintenance program covers preventive service on a set interval, brake and engine diagnostics, DOT compliance inspections, and documented service history for every vehicle. For light- and medium-duty fleets in Greeley, Truck City Service builds and runs that program through our fleet service program, scheduled around your fleet's uptime needs.
One Shop For Every Stage Of Your Fleet's Upkeep
Regular commercial truck maintenance improves fleet performance by catching wear before it becomes downtime. Our team handles everything from routine inspections to engine diagnostics and DOT compliance, so your fleet manager isn't juggling three different shops.
"Fleets that bring every vehicle here get the benefit of one service history and one team that knows their trucks. That consistency is what actually cuts downtime, more than any single repair."
David, General Manager, Truck City Service, Greeley CO

What Greeley Fleets Say
"Sierra did a great job and got me taken care of quickly the morning of my travel."
"I don't normally leave reviews for anything but I felt inclined to after my experience, specifically the rep I spoke to. Matthew was great each and every time we spoke over the phone."
"We were traveling from out of town when our fuel pump on our 2017 GMC went out. We were stranded near Greeley with our two small kids in our vehicle and had to be towed into Truck City. Tammy answered our original phone call & greeted us at the tow truck as we arrived."
