I store my trailer out in the elements. To protect the awning
I remove it and store it inside the trailer. My Scamp
has a sliding back window that makes this easy. When I had my pop-up trailer I left it on full time for 20 years with no issues. They are designed to survive out in the elements. The only issue that I dont like about the new awnings is it didnt come with Velcro straps that wrap under the mounting rail and around the awning so the rail carries the weight
without the bag flopping around. I should have made some and put them in the plans when I mounted my rail. When I go camping I always carry my folding 2 step stool so I can easily deal with the awing and other issues when they arrise. If I was traveling everyday and setting up camp I would leave it up on the trailer until the trip was over.
Its noot hard to deal with the awning if you have 2 people to set it up. taking it down one person can remove it easily enough.
