Thanks for the links mate...the problem is not the build but the little yellow sticker...if it can't be verified it becomes a MOT fail. Just for info, let me tell you this...my man designed and fitted a towbar on my Nissan Patrol...it had no sticker of compliance so it failed the next MOT. I removed the swan neck and re submitted ...passed this time!
Driving in the mountains during the next winter I towed a Q7 and an ML320..STILL LINKED TOGETHER out of a snowdrift for about 5 kms, using the same towbar....it still passed the next MOT, after all that.(just because I removed the swan neck).
It all revolves around the little yellow sticker....put one on a POS, attached with superglue, it will pass....build the strongest version known to man....without the sticker, it will fail! Young ladies who polish office chairs have much to answer for!!
