Equalizer Hitch and Folding Tongue

I'm seriously considering purchasing an Equalizer hitch for my TM2619, although I haven't yet noticed any sway problems on the highway after 400 miles of travel.

I was told by a salesman that TMs with folding tongues couldn't install equalizing hitches.  I find this hard to believe.  I don't see why equalizing hitches can't be installed on trailers with folding tongues.

I would appreciate the input of anyone who has installed an EH on a TM with a folding tongue.  If you have, did you have any problems with the spring arms hitting the tongue?  What are the things I need to look out for.

A word of thanks to all you good people who have contributed to this board.  Your input has been very, very helpful to us as we start on this new adventure with a TM.
