new roof basket option

[VXD959]

I'm considering the Rolla and noticed that the dimensions are 52L x 40 1/2W x 6 Deep. It's my understand that some VXrs have purchased this one.

The one you just bought have a total diferent size in comparison...38 x 16.9 x 9.5 inches...Seems to me that the width is not correct in the website...Is it shorter because of the sunroof?

I will try and find my receipt for my Rolla basket but I paid 139. I think it was hitch anything.com????
