Suit, yourself. I have attached photos of the bar clearly showing movement installed initially by a professional body repair company and then re-installed with a retrofit to solve the problem by a reputable 4x4 company. It still moved after both fittings. As an engineer I can advise you it is definitely not a good design and has basic design faults compared to a HR or a TJM. It has no vertical load retention so when towing a van the "oscillating" forces cause the bar to move, when snatching in a horizontal plane it is probably OK. The AS for design are very very easy to meet, read up on them and you will find a tow bar only has to be able to tow a lightweight box trailer to comply and there is nothing in the design standards I can see about movement, only whether it will carry the oscillating load. Once the bar moves to the extent of the movement it will meet the standards; but it should not move at all. Further if the bar continues to move it will ultimately cause shear stress on the bolts as it is only retained by clamping force, no under chassis retention. Additionally if you have a problem MCC will not reply. But hey, I have done my best to warn you, go and get a HR or TJM, you wont be sorry.
