Customer Testimonials

"SmithCo is my trailer of choice."

I’ve been directly involved in the construction material hauling industry for decades and transitioned my trailer fleet from bottom dumps to side dumps about 20 years ago. In the many years since, I’ve owned over 100 side dump trailers and have evaluated many other manufacturer’s trailers.

SmithCo’s side dump trailer is my trailer of choice. I found the SmithCo side dump is more versatile in what it can haul. The design makes it easy to safely, quickly and cleanly switch between material types and deliver, whatever the load.

The SmithCo design and build quality was what originally attracted me but those two traits also kept me as a customer because of the value they generated in the resale market. On my end it feels good to be connected to the manufacturer of the piece of equipment that has been a major part of the success of our business. It has been a rewarding relationship.

"No better side dump on the market."

First of all I would like to say there is no better side dump on the market. Our oldest trailer is a 2012 SX3 and it is worked hard every day, hauling anything from broken concrete and asphalt to sand, gravel, demo debris, and even brush and logs from clearing projects. This said, it is also the most versatile trailer we own.

This trailer is ten years old and the only thing we have ever done is put tires and brakes on it. We have never touched it with a welder or had to change cross members, straighten frames or anything that a lot of people we know with competitors' trailers have done— and to trailers much newer.

We have just taken delivery of our newest trailer, an SX5, and we look forward to the same great use and longevity out of it as well.

A++ Company!

I recently purchased three SX3 series trailers. I feel that SmithCo has the best all-around, multi-use side dump on the market.

I’ve worked with their sales team in the past and I am always amazed at their eagerness and willingness to help us out, from sales to parts to service. It was the way a purchasing experience should be: SmithCo promptly returned all of my calls, were honest, and stuck to the agreement that was made.

I had a wonderful experience from beginning to end, and I’d absolutely recommend SmithCo to anyone.

A++ company!
