I don't want to get too off topic here but I just
received a link to a site with trailer plans available
from the old mechanix illustrated magazines etc: I
was really hoping to see the old "original" airstream
plans in there (like #1935 Dr. Holman's rig) but no
such luck - but I thought y'all might like to look
anyway.
