John:

I think Bud is out on the high seas up north (noted in the forum)

But just look at the video Jay has up on the home page, see the hand truck, it is about 4' tall, and matches with the top of the blue tubes.  I am on the hard and indeed the stands are about 4' Tall (the tube part, + there is about 6 to 18" more of the threaded part with the pad).  

So if you can not wait until Bud comes back from his cruise the above should help you out. Please also note; those photos are great (if there is something you know the height of in the picture)
