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!
