Hi Paul , my wife loves the trailer so much that she washed and waxed it while I was sleeping in this morning.
The family laughed so much at the kitchen table, I thought you would like that story as a selling point.
She even gave it a name -- "Brutus" lol. Hey, I have an amazing wife. Thank Wesley for us. He helped tremendously.

The folks at Blue Diamond Cargo hooked me up if time with an enclosed trailer for my window installation business. It was a quick smooth transaction. Glad to keep my business local. You guys are the greatest.

Blue Diamond was fantastic from start to finish. They helped me select the right trailer and took the time to ensure everything was hooked up properly and working as it should. I highly recommend them and would happily purchase from them again.

We found this trailer on the internet and Paul was a true pleasure to work with and was very knowledgeable on the various makes and models of trailers here. They installed express track all the way around inside, and I couldn’t be more pleased! Thanks Paul and we will scoop a lot from this little trailer!!

This place can't be beat. I'm sure I drove Paul crazy about all of the specifics because I was so picky about the options of the custom trailer that I had built. He was patient and walked me through every step of the process. Absolutely hands down the best prices around as well... I will definitely be returning for my next trailer!

Bought trailer new in 2021 . Smooth easy experience and had what I needed in stock. It is now 5 years later and they are still very prompt and helpful with anything that I need.

Easiest trailer deal I’ve ever done. Just picked up a Prospector equipment trailer from Blue Diamond Cargo Charleston, and the whole experience was smooth from start to finish. Adam made the process quick and easy — no runaround, no hassle, just straight-up good business.
If I ever need anything fixed or serviced, I know Rob in the shop has me covered. He knows his stuff and takes care of customers like it’s his own gear.
I wouldn’t go anywhere else — especially not that other place across town. Blue Diamond earned my business for life

I needed a dump trailer last min on a holiday weekend, and Adam was amazing he found me exactly what I was looking for and delivered it to my front door the very same day. Extremely satisfied!

Eric and Rob made sure I was ready to hit the road and gave us a 5-star experience. Feels like buying from someone you know instead of a big dealership where you're just a number and a face.

We are so happy to find Adam and his father at Blue Diamond Cargo. They were very helpful with the entire process of buying the trailer. They treated us like family and we will be getting our next one from them when we grow out of this one.

Thanks Adam & Blue Diamond! You guys are the best. I have been looking around for a dump trailer and finally found the one that I want with Blue Diamond. The trailer is made of really good stuff, good quality. Adam gave me all the instructions and helped me setting up the trailer.
Thanks a lot for the whole crew and I will be back soon!!!

Best experience, the trailers are legit. (Durable, led lights outside and installed inside, rhino lined on the tongue) Fast and easy purchasing.

Called this morning to get details on a trailer! Showed up at 2:15 and was out the door, hooked up with title in hand by 3! Eric and his son are stand up guys and fit you with what you need! Best deals on a 6x12 around the Charleston area and man is the trailer MINT!!! He also sold me the best trailer lock system on the market for a good price! Upfront and honest men. Would recommend them to anyone, and will purchase from them again next time I need a trailer!
Edit: had a weld on the spring hanger bust loose. Talk to the warranty team, and got it fixed immediately. They came in on the weekend to fix it so I wouldn’t miss a day of work! Amazing customer service
