I think the place is call BBC trailers or ringwood trailers. There on marroondah hwy, Ringwood, little joint next to a servo. I payed $460 for a brand new 6x4, so why buy second hand if ya only after somthing simple. I hope this helps.
Yeah but the $460 trailer is only light duty, I think its rated to 250 kgs and the next one up was rated to 500 kgs. But 250kgs is fine for my bike, my sons quad and whatever else I want to take camping.. I heard this joint is selling them even cheaper now ($420 I think)
