The main difference is that the orca is a true universal coupling with 360 degrees articulation in all directions.Have a look at the O'briens trailer site at http://www.obrienstrailers.com.au/default.html The coupling is found in
accessories.
The treg on the other hand has a limitation in the vertical movement of 23 degrees up or down. The treg can be viewed on the tregtrailers site at http://www.tregtrailers.com.au/couplings.htm
I have had a treg for 9 years & have not had any trouble with it. Have dropped down some vertical
creek crossing at The Cape also.
If you contact the maker on his website I'm sure he will tell you were you can buy one in your area.
