That is whatshisface's(I forget his unique name)...lead technician at Columbia Overland(http://columbiaoverland.com) in Bend, OR. I've seen that 404 in person, such a sweet rig with the heated ambulance box.
Close, it's actually Thule's he's our service writer. I think he "might" have it sold to a guy in Florida. Should know more this week.

If you're bummed you missed out on the sale, here's your chance again. The copy in the ad says he bought it on the west coast, drove it to Florida, and does not need it for whatever he was going to need it for.
(I am no relation, and know nothing about the truck or the owner. I just spend too much time on the internet.)
