I have a Yakima rocket box that I have owned for about six years. Got cross bars and towers for my old car (94 Caravan).
I haven't tried them on my Pilot yet, but I don't think that the mounting u-bolts are wide enough to fit around the Pilot crossbars. I didn't have a lot of luck finding wider mounting u-bolts but would be interested in hearing others' experiences.
Having most of the hardware already, I'm looking for lowrise towers on ebay.
