Any wisdom/comments about having drop down stairs installed to a crawl
space would be appreciated.

Yea. Why? Do you like go down there and get drunk? Just how high is this
"crawl" space? Isn't it accessed from outside? Where would the stairs be
when they are up? In the house?! I mean the part that normally is out of
view when it's in the attic.

Obviously having problems envisioning this one.
