Looking at the links, neither bumper is tow rated. I have a simular bumper to the Pro Comp. I have the Smittybilt Rock Crawler with D rings. The tow hitch accessory is for light duty cargo baskets or like a bike rack. There are no hoops in which to attach trailer safety chains. You could weld some on, but there is not really a lot of support on the back side of the bumper to hold up a trailer in my opinion. If you are just looking for a bumper with D rings and not worried about towing, either one is a great choice.
