Not true for the DC-10 and MD-11.  The DC-10-10 and -15 lack the center
post while the -30 and -40 have it, as do all models of the MD-11.  Use
of the center post, on aircraft so equipped, is optional, however.  This
has come up in the newsgroup a few times in the past -- you might wish
to peruse the archives (

Beyond that, JAL had some DC-10-40(D) aircraft which were converted from
normal -40 models by removing the center main gear, amongst other things,
and may also have some which were built that way.  The attachments and
other parts were still there so they could be converted back to standard
-40 configs including the full complement of landing gear.
