The OP said "The vent is run under the house, about 10 feet to the
outside wall."

To which I said: Can you get a 2" shop vac hose down there, maybe with
an extension from another shop vac hose?

I'm talking about a extension on the vac hose, not the power cord.

That's what I thought you meant, but I thougbht you meant that so you
could leave the vacuum outside and only take the end of the hose to
some place in the crawl space.

I was concentrating on "under the house" and you were concentrating on
"10 feet" in the same sentence.

The hose on my shop is barely 10' long with both straight tubes
attached to the flexible section. Considering the hose has to be
attached to the vac, and considering the straight pieces probably
can't be pushed into the vent, I'm guessing he'll need an extension if
he wants to blow (or suck) out the entire length of the vent from one
location.

OK. What I meant by holding my hands [cupped] around the ducte was to
seal the ducte so that I only had to put the hose a couple inches into
it.

Elther plan might work. Maybe Jim will let us know what happens,
although I understand how these things drag on for months.
