Greatest weakness of a chinese trailer will be the stubs and axle welding. Exposed to the elements and usually the first to go when a heavy load is applied.
If you're thinking of making your own, the most expensive parts are the same parts - hubs, stubs, and steel. I can buy at a pretty good trade price, but even then, the cost for twin axle springs hubs, stubs and coupling will work out over five hundy if you buy decent brand stuff here in NZ.
