why would it need an SVA test? its not a trailer chassis, its an alko chassis conversion. the razorback comes with a flange and is bolted to the specially ordered fiat cab. the chassis was from an earlier ducato so already had the flange. i just unbolted it, got an adaptor flange made and bolted it back together...handbrake and brake system was still on the alko part...done it in a day.
