Based on what you listed I believe what you have is a 17 foot awning so for a replacement the Solera 12V XL Power RV Awning - 17' Wide - Extra-Long 9'8" Projection # LCV000334961-362243 would be a great option. It's the exact same width but would project out further and also is a powered which means you wouldn't have to manually crank it in or out.
I attached an install/review video for more info on it as well. view full answer...
