I just had the same issue on my 29M. The sewn in lights on the awning started coming loose due to sun exposure rotting the threads. Looked at replacing the awning but was more than I wanted to spend. Purchased a Carefree of Colorado replacement light strip with 3M backing and attached to side of RV right where the awning strip was to begin with. Perfect fit and can’t tell any difference.
