About 4L Truck & Trailer Repair
Welcome to 4L Truck and Trailer, your trusted partner in heavy-duty diesel repair. Nestled in the heart of Childersburg, AL, our facility has proudly served the community since 2012. With a spacious setup of 11 bays and a dedicated team of four skilled technicians (and growing), we are committed to providing top-quality service to all our clients.
Our Journey
4L Truck and Trailer was founded by Joshua Lamberth, whose passion for mechanics began in his youth with a love for hot rods and fast cars. Inspired by the dream of building hot rods for a living, Joshua ventured 700 miles away from home to attend a prestigious tech school. His professor stepped in and encouraged him to do better. This Professor changed his entire life by writing a recommendation letter, which he still has framed at home today Standing tall at 6'5", he was advised to shift his focus from cars to diesel trucks, a decision that set the stage for his future. Joshua’s early career involved rigorous training and notable challenges. After a tenure at International and Montgomery in Birmingham and various other roles that honed his skills, Joshua’s vision for a local shop became a reality. Driven by a desire to provide for his growing family and to serve his community better, he transitioned from working out of his house to establishing 4L Truck and Trailer.
Our Philosophy
At 4L Truck and Trailer, we operate like a family. Our employees are not just workers; they are integral team members who contribute equally to our success. This ethos extends beyond the workplace, as our team often comes together to help one another, like assembling a swing set for Joshua’s children.
We strive to exceed expectations in every task we undertake, aiming to outperform dealership standards. Joshua, known for being a bit of a tool addict, ensures that our shop is equipped with the best tools in the industry, enabling us to handle even the most challenging diagnostics and repairs.
What Makes Us Unique?
Our commitment to excellence is matched by our dedication to solving complex mechanical puzzles. Joshua is renowned for tackling the "weird stuff" that others shy away from, continuously updating his knowledge and skills to stay at the forefront of the industry. We also pride ourselves on building specialized components like AC hoses, originally made for the International dealership.
Thriving Through Challenges
Since moving to our current location in September 2019, we’ve experienced significant growth, especially during the challenging times brought on by the COVID-19 pandemic. This growth has not only sustained us but also led to the establishment of an accompanying trucking company.

With the continued support of our community and the unyielding dedication of our team, we are excited about what the future holds.

My RV broke down on the way to a family vacation. Josh stayed 7 hours after his shop closed on a Saturday to wait for my vehicle to be towed to his shop. He then had my vehicle back on the road within an hour. Due to his care and attention to detail, we were able to continue our trip with minimal interruptions. I highly recommend his shop, especially for this man of character. He made a point to ensure Father’s Day 2026 was a great one.

Really like these guys. Had my F-350 back on the road quick. I live an hour away, and I’ll keep coming here for my truck needs. If you’re looking for a shop, look no further. I’m very happy with the service from 4L.

Excellent service thanks to Josh and Team! They were extremely helpful in quickly locating the part we needed and getting our unit repaired fast so we could get back on the road with minimal downtime. Everyone was professional, knowledgeable, and friendly throughout the entire process. Their customer service is truly top-notch, and you can tell they care about helping their customers. Highly recommend this shop to anyone needing reliable truck and trailer repairs!

Good, honest shop. 07 Duramax shut off going down the road. These guys diagnosed electrical issues and repaired, cost was less than I expected it to be.

They were transparent about the costs and didn't try to overcharge me. I highly recommend them for any truck repair needs! This is family owned business very nice people.

They have great techs but the owner looked at my truck personally. It felt like no time at all and he had it diagnosed and fixed.
