Already stated my lack of expertise, but I think you will find the Australian manufactured trailers have the square gaurds, the American ones the round. Obviously it is easier to sit a beer on a flat surface......
One ton trailers are the same, Aussy are square gaurds, Pommy are round.
Considering that it is the week end, I would have thought you would have left on your border raid by now, maybe you need some tips from Bob.
