ABout All in One Truck Center

All In One Truck Center got started back in 2023, but the story goes way further back than that.

Contact Us

Pedro, our founder, originally ran a diesel shop up in New Jersey. That place had a rough rep when he first took it over—but he stuck with it, turned things around, and built up a loyal base of customers who trusted him to do the job right. After moving to Florida, he decided it was time to start fresh—so All In One was born.

We’ve been in the same building since day one, and while the shop’s grown, the goal hasn’t changed: get to know the folks who come in, figure out what their truck or vehicle needs, and fix it right the first time. Pedro’s the kind of guy who loves big trucks and even bigger challenges. Solving the tough stuff is what keeps him going.

Today, we’ve got two locations and a solid crew of six skilled techs working across four bays. Everyone on the team respects each other and keeps things professional. No drama, no gossip, just good work and a crew that’s easy to get along with.

When people ask what makes us different, it's this: we stand by our work with some of the strongest warranties around, and we don’t believe in cutting corners. The quality speaks for itself, and our customers notice.

I had a great experience here. The quality of service and professionalism of the staff were terrific. There were some issues with the truck, and after bringing it to this location, they were able to fix the problem right away.

Go see Pedro. I had a major gear failure on a 2014 Volvo and the shop worked with me to get it resolved. He allowed me to get some parts that saved me some money and he stuck with the truck til it was done right.

I spoke with both Pedro and Alonzo about an issue with my fuel/water separator. They were both very patient and understanding and gave me great advice to try to save me from a tow bill.
