Hi, I'm new to the forum. Bought a 110 about 2 months ago. Problem is, I tow a trailer with a laden weight of about 550 kgs. My towbar seems to consist of just a plate that's bolted on and the ball itself. It appears to be missing a pair of "arms" or something that joins it to the underside of the LR. Is this dangerous? Can these arms even be bought separately? The main plate seems to be bent inwards slightly already. Not from my trailer but from previous usage I suspect....any advice appreciated...
