Gunnells Services LLC

We’re excited to begin expanding our in-house fabrication capabilities through TIG welding. This investment allows us to take greater control of the design, fabrication, and repair of cooling, exhaust, and EGR systems.

By bringing more of these processes in-house, we can reduce dependence on outsourced components, improve quality control, and develop custom solutions for applications where off-the-shelf parts simply aren’t the best answer.

At Gunnells Services, we’re always looking for ways to improve reliability, serviceability, and overall system performance. These new capabilities will allow us to engineer and implement more effective solutions while continuing to provide our customers with the highest level of service and support.

🔥 The heat is brutal, but the work still has to get done. We’re staying hydrated, taking care of our crew, and pushing through to keep our customers taken care of. If you see us out there sweating, just know we’re giving it everything we’ve got!

Some people see a muddy jobsite, a crowded parking lot, or a piece of equipment buried in the woods and start looking for shortcuts.

We don’t.

At Gunnells Services LLC, we believe the job deserves to be done the right way, no matter where it’s located. Whether we’re working in a fleet yard, on a construction site, in the middle of a field, or deep in the woods, our standards don’t change.

The right tools. The right diagnostics. The right repair.

Because “good enough” doesn’t get trucks, equipment, and businesses back to work.

We do it right. Onsite. Every time. 💪🔧🚛

We’ve been running hard lately, and we’re incredibly thankful for it.

The phones have been ringing, the schedule has been full, and our service trucks have been putting in some miles. Every call, every repair, and every customer who trusts us with their equipment is a blessing we don’t take for granted.

To everyone who has chosen Gunnells Services, thank you. We’re doing our best to keep up with the demand while continuing to provide the quality service you deserve.

Busy is a good problem to have. God is good, and we’re grateful for every opportunity. 🇺🇸🔧🚛🙏

Whoever said service trucks aren’t off-road vehicles has never followed us to a jobsite after three days of rain. 😂

Nothing builds character like:
• sliding sideways through a pasture
• dodging mud holes the size of swimming pools
• and unloading tools while your boots disappear into the earth

At this point our service trucks qualify for the Dakar Rally. 🛻🌧️🤣
