Fleet Maintenance Where Your Trucks Park
Yard Service During Off-Hours and Weekend Dwell Time
Your trucks already sit idle overnight and on weekends. We bring fully equipped mobile service units to your terminal or staging yard and handle preventive maintenance during that downtime, so every unit is ready when the next shift starts.
Why Yard Service
Follow One Truck to the Shop
Here’s what a routine PM costs when the truck has to leave the yard.
6:00 AM: The Drive Over
A driver who should be running a load drives an empty truck across town to the shop.
Hidden cost: unbilled driver hours and deadhead miles
8:00 AM: The Wait
The bay isn’t open yet. The driver sits in the lobby on the clock while the truck waits in line.
Hidden cost: a driver paid to do nothing
1:00 PM: The Extra Day
The shop finds a problem and needs a part. The truck stays overnight and misses tomorrow’s dispatch.
Hidden cost: a unit out of rotation and a load reassigned
Next Day: The Drive Back
The driver goes back for the truck: more empty miles, more hours, and you get a paper invoice with no photos of what was done.
Hidden cost: deadhead miles again, and no record of the work
With ENCINA POWER, none of that happens.
With on-site fleet maintenance, the same PM happens overnight during dwell time your truck was already spending in the yard. No driver hours, no deadhead and a photo and video record of the work in your Fullbay fleet portal.

On-Site Service FAQ
Yard Service Questions
Are full PMs performed in the yard?
Yes. PM-A, PM-B and PM-C are all completed on-site. Our mobile units carry the equipment, fluids and common parts needed to finish the job without moving the truck.
When does the work happen?
In a service window we agree on in writing, usually overnight or during weekend dwell time, so your trucks aren’t pulled off routes.
Can trailers be serviced on the same visit?
Yes. Box trailers, reefers and flatbeds can be serviced alongside your tractors, including structural PMs.
Which areas do you cover?
Our Romeoville and Will County hub serves fleets along the I-55, I-80, I-355/I-88 and I-294/I-94 corridors, from Joliet and Elwood to Naperville, Oak Brook and greater Chicagoland.
How is on-site service priced?
Pricing is provided in a written proposal, following a complimentary yard audit of your fleet.
