It's not a big operation so you'd have to get on his schedule. I liked the fact that he took the time to sit down with me and discuss everything about the trailer and even made some suggestions as far as the gauge of the metal, suspension, how to setup the sides so they could be removed, etc. I run the trailer across a creek so I wanted externally greasable wheel bearings and the jack had to be installed so it wouldn't catch on the creek banks.
He only builds trailers on order so you get exactly what you want even down to the color, electrical connector (I wanted a seven pin) and the tire size, etc. I wanted a tire that was interchangeable with some other equipment. l use the trailer only on the farm but it is road legal with brakes, lights and reflective tape.
After everything, I believe I saved at least $1,500 over the price of dump trailers I've seen advertised. Of course you're buying directly from the builder so there's no dealer markup.
Good luck, Darren
