re-attach couch arm

Hi all,

Our Lance 1475 trailer came with the couch that has two
"recliners" (really just footrests that swing up), though I would
have rather had the two captainschairs configuration.

In any case, the arm at the bed end of the couch...

...has become quite loose, it's barely attached to the frame of
the couch.  So far I haven't been able to see how its attachment
could be repaired.  I've looked under it with the footrest up, but
not seen anything helpful.  I need to get back out to the trailer
and just try to wedge myself under there, but in the meantime I
wondered if anyone here might have suggestions.

I've tried searching the web for any guidance, but have come up
empty.
