Came up with a different way of protecting my awning and keep the tree debris out of the valley between the trailer and the awning while is rooled up.
I looked at the Pro-tech product that is advertised in the trailer life and motor home mags. I wanted something like that, but did not want to pay $100.00 either. So I looked at the local home improvement stores and only found very heavy gauge PVC for plumbing and drainage. So I looked at the heating and cooling ducting, found a 5 ft by 4" sections that would slide over the awning, just like the way the Pro-tech product says it does.
The to keep the debris out of the channel from between the trailer and awning, I picked up the drip edge that is normally placed under the your houses roof's shingles at the edge by the rain gutter. To accomplish this I lined the drip edge while the ducting was on the awning, to cover the gap. I just need to finish completely painting it.
