I made a mod to my bag awning that made it the most robust awning on the property this summer.
Last year, a surprise downpour broke our awning support rods while we were at the Sunday AM worship service. We used a wrench as a splint to get us through that trip, but we're looking to replace the rods for this summer's vacation.
When we couldn't get replacement parts for less than the cost of a new awning, I went to the local home improvement warehouse and got two pieces of rigid aluminum conduit big enough to cover the existing poles and that would slide over the pop-in connectors camperside. Cut these to the right length to extend the awning fully.
If downpoles are weak or bent as well, get PVC pipe that will slide over them. Since you're looking at vertical force, the side bend rigidity won't be an issue.
After installing both of these, I guyed the awning with a strap and dog tie out stakes. The only way we'd lose it now is if it rips the bag from the camper itself.
