I was recommended to use Aranda Towbars by the trailer company where I bought my trailer from.
It was a great surprise to find that the staff there can go to your home to add the towbar to my car at no extra cost.
The towbar looks like it is of high quality plus I have the ability to adjust how far the towbar can come out from the back of my car. When not in use - I can slide it in further and lock it up.
