I have a Wilderness Sport Series Roof Rack (Garvin Industries) for sale. It is used but in good condition. It came off of my D90 which was a bit of a modification as it is advertised to fit Discovery, LR3 and Range Rovers. It has a dual jerry can holder attached to it and that is included in the sale. Both could use a fresh coat of paint and a couple of new bolts and washers. The can attachment was bent at some point but has been corrected. With new paint it will not be noticeable. It retails for around $600 and a dual gas can holder is about $150 new. It is located outside of Seattle but could be brought down to Portland upon request. Local pick up preferred. Make me an offer I can't refuse.
