Just to put this topic to rest, I decided to purchase the UltraFab jack and try it out. Purchasing another shank for the Blue Ox just wasn't appealing at the price I found and the weight of the one I have already breaks my back a longer one probably adds another 10 pounds.
At the very worst I spent $150 to see if I can open my tailgate with the UltraFab and if not, I bought from Amazon and they'll get it back. At any rate the UltraFab is probably twice as good as the generic FIC noise maker that came with the trailer.
Thanks for all of the suggestions and comments.
