What Our Customers Say
Diamond Truck Bodies goes out of their way to make your custom flat bed perfect in every way. Everything they said they would do they did beyond expectations and the delivery date was sooner than promised. There's not a flaw in their custom work. We dealt with John Cooper and found his attention to detail and his willingness to give us anything and everything we wished for was truly amazing. It was the best buying experience we've ever had.
I want to thank Parts Manager Anthony at Diamond Truck Body. I bought a cab guard and outriggers for my Super Duty truck. When a minor issue arose, Anthony quickly resolved it. He was professional and even helped me get my truck back on the road after the starter motor died in the parking lot. I highly recommend this place for all work truck needs.
Highly recommend the team at Diamond Truck Body — both Anthony and Mike made sure I was getting exactly what I wanted in a rack. They were in constant communication from start to finish. The job was completed ahead of schedule and I could not be happier.
I was searching for a cover to protect my tools in my service bed. Then I found Diamond Truck Body. I sent them the dimensions and they sent me a cover. The instructions were easy and I installed it in two hours. Tons of people have asked where I got it — you know it looks good.
