Not a Noob, but seek information on Sunrader trailers

[rxinhed]

I am seeking information about the depicted Sunrader Trailer. I have an ag-trailer frame that I'm building to haul behind my Mighty Max. The ag-trailer is similar in layout to a Bantum M100, but was used for a water pump or air compressor, and is now equipped with 38" Toyos. From the pictures only, I cannot the size of the trailer, but it looks to be about 4 x 6 feet.

Does anyone have experience or advice?
Thanks, Russell
