Never heard of them and based on the fact nobody answered the 1st question. They probably was nobody on the board with any experience.

But that doesn't mean they are bad or good.  Just do reasonible due diligence.  Look at what type of metal is used to build the trailer.  Most trailer manufactures list the guage of the metal they use, So compare.  Look at the welds and how tight the pieces of metal were fit together before welding. nice tight joints mean some precision was used in cutting and fitting parts together.

Most trailers use a list of off the shelf parts.  Axles, fenders, lights, couplers, windows, tires  are often all purchased from parts suppliers and are common between several brands of trailers. The manufacturer of a trailer is often an integrators of these many parts and the metal box he has built. The concern isn't so much about the componets themselves, but if they were installed correctly. A dexter axle on a no name trailer will perform as well as a dexter axle on Platinum trailer IF it was installed correctly.

With a little snooping around the trailer, you should be able to tell if it's well built and safe.
