Just bought a brand new Rockwood 2280BHESP, picking it up on Saturday. We also have two Hobie Compass Mirage Drive kayaks, the bare hulls are 68lbs each. I have added fishing tackle management systems to the floors, and some other non removable add-ons, so I figure the hulls are about 75lbs each now. Yakima Jaylow kayak cradles are 12lbs each, so in reality, I am looking at about 175lbs total. Rockwood rates the factory roof racks at 150lbs, I also have an air conditioner on the roof. Will I be pushing it too hard? I feel like everything I know says to baby the roof of your pop up.
