We had a patio cover that was shaded with shade fabric purchased at Lowe's. I sewed panels that we put grommets in. We purchased rope to loop through the grommets and eyebolts were installed on the wood beams. Something like that could be built for your rv. It was an easy project, you don't have to be a seamstress to make the panel. I reinforced the fabric with other strips of fabric where the grommets were going to go. We took it down in the winter for more light. I don't have a picture. I have seen something like it in a Sky Mall catalog, think they call them shade sails.
