Sorry--I misread your reference to the Hullavator. Actually, I was never certain it would work with the OB, because of the wide sponsons. I know that the Thule J-saddles do not work with the OB for that reason.
Dang anasasi--wish I could help you out with the pics, but I would have to locate them the same way--with the Search or Find function. With 370 posts here and over 2,500 posts on KFS (where a lot of the same or similar info also got posted), I think I will let you do all the heavy lifting!
Speaking of which, I used to have a Vanagon and my Trooper is about the same height now, so I have to carry a step ladder around now in order to use my rack. Thus the reason I sprung for the Trailex trailer--even though I don't like fooling with trailers. But once you get used to the idea, you sort of forget you have one back there (until you have to back up, that is
). And a clean and jerk to a height of about 3 feet (probably less than one hern) sure beats the over the head number with a rating of nearly 4!) Even with my home-made loading bar from an extra Thule bar and some SS U-bolts, it still required a ladder to get the other end elevated without aggravating my rotator cuffs.
With regard to the Igloo cooler and the ATI rodholder, I can help you out with that one since it is all covered in a single post here.

Also here is my post about the Trailex trailer over on KFS. Have fun!
