POV: Katie & I said “hold on… run that by us one more time.” 🤨😂

Next thing you know every invoice is spread across the desk, calculators are working overtime, and we’ve somehow launched a full investigation. 🧾🔎💀

Please hold while we figure out who needs to show their work. 😂

🛠️ TUNE-IN TUESDAY IS BACK! 🔧🚛

Your fan clutch staying on ALL the time? 👀 Before you assume the fan clutch itself is bad, there could be something else telling it to stay engaged.

This week, Allison is breaking down how to tell if the fan clutch is actually the problem — and what else could be causing it to stay on. ⚙️

Because when it comes to truck problems, finding the actual cause matters just as much as fixing it. 🔧

Tune in every Tuesday for tips straight from the shop at Haggai Truck Center!

Unfortunately for everyone at Haggai Truck Center, these two came as a package deal. 😂🔧

You get Allison, you get John. You get John, you get Allison… and somewhere in between the arguing, aggravating, and carrying on, the trucks DO actually get fixed. 🤣🚛

Would not recommend separating for too long. Results may vary.

SHOP’S CLOSED, BOOTS ARE OFF!

We work hard around here, but Labor Day calls for a little break. 😎
Haggai Truck Center will be CLOSED Monday, September 7th while our crew enjoys the long weekend!

We’ll be back Tuesday with the shop doors open, wrenches turning, and trucks getting worked on. 🚛💪

Happy Labor Day from the HTC crew!

🔧😂 WHO IS MORE LIKELY TO: ALLISON VS. JOHN EDITION

They work on trucks together all day… so naturally, they know WAY too much about each other. 😂

We put the Haggai Truck Center besties to the test with a little “Who’s More Likely To?” and let’s just say… some of these answers came a little TOO quickly. 👀🤣

Who do YOU think is the troublemaker of the shop? 👇
