This silly looking thing helps get the leaves and branches off of slide out. Take a measurement of your slide out when open. Get a piece of carpet the same width. Get a piece of 1x2 about 1" shorter in length. Attach the wood with wire ties through the carpet on one end. Use either twine or thin nylon rope on the other side of the carpet. To use: Have one per lift the carpet to the top of the slide out as you pull the rope that was previously thrown over the top (you are now on one side of the trailer and the person is on the other). Gently pull the rope or twine with the carpet side down to clean off the branches and leaves. If you attach rope to the wood side too, just add soapy water and both people can pull back and forth to scrub the top of the slide out.
