I've thought about jbars but worried I would have to unload everything out of the kayak like my hcrate. The outback shown in the picture is dead center on the trailer so I have room on both sides. I considered going the pvc route for the 2 on the outside, then on the inside find some way to put a raised section with crossbars. So id have 2 on the current bars, then one more on a raised section in the center
