I talked to the place in TX. They have a demo, but the trailers are an 8-week order item.
The purple trailer pictured above in made by C-Way in the Ukraine and is not currently imported into the U.S.A.
Unison from Australia is running behind projections, but still seems to be working towards a 2012 release. I like David's design and approach, but he is working on a M109 matching trailer and a GL1800 matching trailer. I would expect that a "generic-style" trailer would be down the list a bit.
