We are going to get a Hayman Reese for our Patrol. The old one must be a Nissan as HR said their name is clearly visible on their products and i can't find anything on this one; Patrol was purchased 2nd hand.

It did not last the distance pulling our caravan, and as the auto Patrol is listed to tow 2.5 t, it may have only been suitable for up to that weight. We have the WDH bars fitted. We were lucky not to do any other damage when it snapped (other than the safety chains which now need replacing).
