Travel Trailer Front Cap Cracking Aluma Lite

Thanks so much for the follow up. The cracks are in the plastic front cap at the very top. I looked and each one is just under where the screws mount to the roof. The cracks are deep and the plastic is completely separated. I have some heavy duty duct tape on it now and will wait to decide what to do. I will drill the holes tomorrow, that is a very good idea. I appreciate any other advise you may have.
