From Shack: Sorry I didn't mention it along with wind deflectors in my last post, but Herrington also has a rear cargo liner which looks to be of excellent quality in black, tan, or grey. I've been looking for one without the partitions on the Mercedes version for protecting cargo area when carrying big loads. It has a 3 inch lip all around and costs $89.95 vs $105 for the Mercedes version from Clair's. (Catalog #MS228; Herrington 1-800-622-5221).
