after a little input on a trailer i picked up in lieu of payment for some work i did.

It only has surface rust and god knows when it was last registered because there is no build plate on it nor a vin number anywhere.

Now what i need to know is if it is ok for a 700kg boat.

The frame is c-channel 75x45x7mm the draw bar i will be replacing because the bottom is rusted and it currently is 60x60x5mm

If the frame could handle it i was looking at putting on a dual 1400kg braked Axel set
that i found on ebay for 600 bucks and that way getting it rated at 1300kg for the blue slip and rego



Thanks
