Several bits of very important information are missing from your post and need to be provided before a good assessment can be offered.

1. What brand of awning do you have? Has this just started or is it an ongoing problem?
2. Is it possibly winding up "backwards" In other words, under the roller tube rather than on top?
3. Is it properly aligned, no wrinkles in the fabric while rolling up? Do the support arms bind or are they bent/bowed?
4. Have you felt the front end of the awning tube during operation? The motor is located there and is it hot?
5. Do you have a proper sized battery in the trailer and is it fully charged?

Providing answers to those would help anyone who might want to give you some advice......
