Neil,
Yes, it is not cheap. It is stainless steel, multi-sectioned, and very long when fully extended (and, I think it is a lcensed product).
Some people have reported installation problems. I have installed two and am working with a third. They installed fine on my regular trucks - I'll know soon about putting one in/on a COE (the outer cowl is the same but the sheet metal on the inner side-wall is different).
