Vaughan ,
When I was adding my slide toppers , I had a lot of contact with Autumn over at Carefree.. She was on the ball ,sometimes it was a day or 2 for an answer , but other than that she was good.
As far as the size and color.. I would think that IF you called the Redwood/Crossroads customer service with your VIN # they could tell you most of what you need..
BUT , , When I added my tops to the slide toppers , my dealer was cheaper than Carefree direct.. Maybe you can also try Tiera RV ?
