I guess this is where the "what is more important to you" statement comes in...you have a bigger kitchen inside (269 BDHSK), we have a covered kitchen outside (317 BHSK)..
I had the big awning replaced under warranty 90 days after i received the unit. the parts alone were around 1,400 bucks...I would imagine that adding a custom awning to the back of yours would be in the ballpark of 2,500 to 3k
