Thanks Ace. We plan to integrate front load racks it into our expedition frame and tongue rack. There have been a few items with higher priority such as the expedition frame and the mulit-directional hitch.
As far as the bar above the tailgate, we don't want to mess with that. The tube is an integral part of the support system for our tub. I'm not sure if I've posted pictures but we can and have loaded a 4 wheeler on top of our lids. We are thinking of selling a trailer without a lid for a lower price though, with this design we could possibly do away with the cross support and treat the trailer more like a pick-up.
