An amazing innovative product that I personally cannot endorse more. This will save your back, your large dog joints, your small dog’s mis-leaps and more. No heavy and bulky ramps or hoisting things over head to the roof rack. By simply inserting into your tow hitch, the Twistep rotates from under the bumper to create a step. I use this product daily and it is sturdy and easy to operate (even one handed and in the rain). Everyday I applaud this product.
