I think Yakima will be calling you soon, offering you a consulting position in their R&D department. The thing is stout to say the least. The 150 lb limit is for while you are driving at 70 mph. While it's parked, I think you could hold a dance contest on top of it, or pitch a tent. Some sort of quick release attachment would be an improvement, as would be the table legs. Maybe the legs could be incorporated into a perimeter railing. Then all you will need, is three more yellow boxes, which could be used as chairs, for a table for four. We will do the boxes foam core this time, vacuumn bag them, lighten them up.
