Thanks to all who responded.  A used Dennis  Haynes hitch was found and is
on it's way to me.  The U-Haul hitches are  both tow loop mount types, no
good for carrying the Sherpa.  Sure looks  like the Dennis Haynes hitch is the
only frame mounted class II ~ class III  receiver hitch out there.  Well,
maybe not, there is the one from Burley  Motorsport that looks right also.
Anyone tried or seen this one up  close and personal ?

Cheers,
