I hope you're doing well. I'm reaching out to clarify a technical detail regarding your products. Specifically, I'd like to know if the Annex B and the awning options are compatible with my existing model. It's important for me to ensure that these components will work seamlessly together. If you could provide some insights or specifications that confirm their compatibility, I'd greatly appreciate it. This information will help me make an informed purchasing decision. Looking forward to your response!
