We own and run a transport company called T&S Transport Services. We had a custom truck trailer built by the team at gal-trailers. Which is used for both business and pleasure. They went above and beyond in keeping in touch with us during the build process. We highly recommend gal-trailers!! We will definitely be back with more custom builds for the team ?

I couldn't be happier with my experience at Gal-Trailers! From start to finish, their team was professional, knowledgeable, and went above and beyond to meet my needs. The quality of the trailer is top-notch, with exceptional attention to detail and durability. They took the time to understand exactly what I was looking for, and I ended up with a trailer that fits my requirements perfectly. The customer service was outstanding; they answered all my questions and provided helpful advice along the way. Highly recommend Gal-Trailers for anyone in need of a reliable, high-quality trailer!

The service and communication during the build process was always great. Questions answered and progress was very informative. A real pleasure to deal with. When I picked up the trailer the manager explained everything I needed to know. The quality was better than I expected, and I would really recommend Gal Trailers to anyone. You will get great service and quality products.
