I don't have an awning on my bus.
I do have an one on my trailer RV.
2022 was not a stellar year for RV awning manufacturers.

"In early August, the National Highway Traffic Safety Administration (NHTSA) issued RV recalls that could affect more than 50,000 new RVs. The RVs come from seven different manufacturers."
"The issues in the majority of the RVs are mainly due to a faulty and potentially hazardous awning."
----------------------
I do not know the number of awning manufacturers, who supply these builders. Likely the same brand(s) who sell retail aftermarket.
When you do narrow your search, please update this thread.
