"Depends on trailer weight up to 750kg car plates, unless trailer is braked own plate, you can't disconnect brakes to comply, +750kg own plate."
You've lost me there. Are you saying that if the trailer has it's own brakes (I am now thinking of buying a trailer in Spain with brakes) that it must have it's own reg plate? If so I can get Portuguese plates made up.
I can buy a new trailer for what I've been quoted to deliver the boat.
Thanks.
