The saga of my junk rig.....I need suggestions....

Just to clarify, it does NOT leak inside. The bunk ends leak around the lower part of the seal on the sides because the seal doesn't stay in the channel.
I lowered the awning a few minutes ago to check on it and it actually came down right. Hmmmmm...If I can find awning repair tape or patches it may be salvagable for another season or two. I do caulk what I can see when I come across it.
