I purchased this a couple of weeks ago, brand new in the box. I bought it to go with a stock seat because I needed more comfort and it raised me up about an inch which helped greatly. To my surprise I was able to re-purchase a RDL that was made for me when I owned a 2005 FJR. That seat is fantastic and I have no use for the Airhawk.
It's seen minimal use and is listed here for sale. It cost me $94 shipped, I'll sell it for $75 delivered within the lower 48.
Please PM me for paypal info (add 3% for fees - or pay friends and family). Thank you, Barry
