We had two challenges. There was one whole on the top that was not lined up correctly and wouldn’t allow us to attach the top center cross bar. It required taking the main top bar mostly apart then putting the crossbar on and reconnecting the main top bar. Then we have one bar that runs through the tarp at the end which becomes the handle that has popped apart twice while putting the tarp from one side to the other. We are trying to determine if that happened when the tarp was pulled uneven.
