[VAC] Roof AC NOT okay on '55 FC??

[Berger Roger <air7722@xxxxxxxxx>]

How can you tell how many frames you have, by the
rivets?  I have a 55 FC with (I think)Duo-Therm AC
that was put on there by the previous owner.  Did you
ever try to support the AC during travel only?  Maybe
a 6x6 vertically between the AC and the floor would
help.  Plus you could burn it in the winter for heat.

By the way what does the Duo run on?  110AC and/or
12vdc?  (I haven't figured how to even plug my FC in
yet - the previous owner died before he could show me
anything)
