“Show Us Your Rig" Contest Winner

Everybody meet Nick Fortune from Fortune Trucking out of Washington, ME. This green Western Star is the real deal — and you can tell it actually works for a living.

We asked you to show us your rigs, and you guys delivered. But this one stood out. Pride of ownership. Maine tough. That smile says it all.

I just delivered his prize: a customized cup displaying his logo, and this fresh hat/shirt combo.

Thanks to everyone who entered. We see you out there, and we’re proud to keep your trucks running. Keep your eye out for the next contest, maybe you’ll be the next winner!

Fall special-PURUS 50/50 nitrate free, extended life coolant

$9.99 per gallon
$49.95 per case of 6 - 1 gallon free!
Cash or account. While supplies last.

If your truck or boat is 2010 or newer, most CAT, Cummins, Paccar, and Detroit engines now require nitrite-free, extended life coolant.

Why it matters:
Nitrite free — what OEMs spec now, uses Organic Acid Technology to protect modern engines. It prevents corrosion of aluminum components and eliminates the need for supplemental coolant additives, lasting up to a million miles or more.

Pre-mixed 50/50 ready to pour — do not add or buy distilled water, no prep needed

We stock it because we use it.

Just received our bulk order today, call us to get yours.

If your shop doesn’t look like this on a Friday….is it really a diesel shop?

Torn apart. Hoods up. Bays full. 4 out-of-frames. 2 in-frames. Transmission job. Suspension/frame rails. AND…still seeing our customers outside on the cement slab to ensure they have as little down time as possible.

Employee highlight: Jeremy Gammon, Diesel Technician

New to us, not new to this - meet Jeremy, he has been working as a diesel mechanic for over 20 years. He came to us from O’Connors, where he took a special interest in engine repairs. He didn't hesitate to jump in and has already tackled an in-frame overhaul and is on to the next.

As a 4th generation mechanic, he started at O’Connors right out of high school. He then moved on to O’Hara Corporation where he worked with marine engines for 7 years. He found himself missing the truck side of mechanics and went back to O’Connors for another 5 years.

Jeremy brings more than just experience to the shop, he’s trained in:
Engine Work: CAT, Cummins, Detroit, Volvo/Mack — from overhauls, electrical troubleshooting, to fuel and aftertreatment troubleshooting
Brakes & Suspension: Air disc, drum, ABS, steering, DOT inspections
Advanced Diagnostics: fault code tracing, wiring harness repair

What You’re Looking At:

That red tool? That’s a counterbore cutter. We cut it, measure it, and shim it to spec.

This is precision, to the thousandths of an inch.

That’s how flat it has to be. Thicker than a hair. Thinner than paper.

Get it wrong? You’ll be doing this job again.

We don’t guess. We measure.
