[A/S] sideways cranker thing?

[Chris Koehn <timberguides@xxxxxxxxx>]

How's that for a description?!
While on Padre Island a couple of weeks ago I met a gentleman with a 
1996 28'. He had a nifty device he lowered his front jack on to. It 
allowed him to move the tongue of the trailer from side to side by 
turning a coarsely threaded rod with a hex wrench. Pretty slick: if he 
were to back his tow vehicle up along side the tongue instead of 
exactly in line with it, he simply cranked the tongue over until it was 
directly in line. He used a Hensley, which I guess is even trickier to 
align than a standard ball hitch. I neglected to ask him where he got 
this thing before he bugged out.
Anyone have any idea of who manufactures this gizmo and how I might go 
about getting one?
Thanks!
