Anyone seen one these yet? http://maloneautoracks.com/toptier.php

I was looking for something at the Malone web site and saw this. I think it is very clever idea! I have a utility trailer I haul a mower on and plywood for the shop. I also have a dedicated kayak trailer too. I looked for an easy way to use one trailer for both and never had a good idea that was easy to remove. Never thought about going up. Kooks pretty darn cleaver to me but since I just rebuilt my kayak trailer I am going to keep it.
