Wingnut60:
Those devices work very well with conventional suspension with the rocker beam center piece (for every inch one spring shackle rises the other end of the dogbone goes down 1") but with the Trailair bladder there is quite a bit more "roll" to the center beam (the whole bladder device rotates but the bladder also expands as weight comes off so you get a magnification of the shackle movement) and you would have to have the good tire up on some sizable ramp to eventually lift the flat one off the ground.
