So, how long should a trailer last Australia? If it’s a painted, light-duty import stored outside, you might only get 5 to 7 years before the rust or structural fatigue makes it unsafe. However, if you buy a high-quality, Australian-made, hot-dipped galvanised trailer, there is no reason it shouldn’t last 25 to 30 years.
The “life” of a trailer is determined by the bearings and the springs. Even a 30-year-old frame is useless if the suspension has snapped. By replacing the bearings every two years and the leaf springs every ten, you can keep a high-quality galvanised frame on the road indefinitely.
