I'm sorry to disagree with itat, but I'm going to recommend the opposite style rack.
We first had this 'platform' style rack:

But, because the rack protruded so far from the back of the coach, it got beat up by dragging on the pavement when we would pull out of a steep driveway (such as at a gas station).
So we got this 'hanging' style rack:

Since the rack doesn't protrude very far before rising up high, it never drags on the pavement. We are happy with the design and the quality.
