Hi JB, Bobby,
It was a production model in the 18 foot size, and I asked them to make it a 20 footer for a few dollars more. I specified the headache rack height, adding D rings, spare tire, (which I welded a place for it underneith), color, etc. BMF Trailer works made it up in Wisconsin. They dropped it off for me free on a trailer run to a trailer place in Elkhart, and I went up and pulled her back home to SC. I used to live up at Kokomo, (in Indiana), so it was an enjoyable trip up and back. Lotsa corn up that way...
There is definately a market for such a trailer. I just don't know why more people aren't making them. It would be a profitable niche to get into. BMF also makes side dumpers as well. But, I don't know anything about them.
