Its something different. Like the fact that you gain the extra space under the bike all the way to the front wheel... Cons, you need to have one of those cargo rails mounted, otherwise it becomes a pain to install and remove when not in use, especially using the bottom tie down mount. Lots of improvements that can be made to this idea... But when all else fails, you could use a cargo net for over the rear to prevent things from sliding out when travelling with tail gate open... Think OZ use to sell them...
