In a previous post says...
I didn't know they make "attic trusses". But if they are as costly as
you are saying, then I'd think using dimensional lumber would be about
the same price, both in materials and labor. I realize trusses go up
faster, but normally a crane is needed to lift them to the roof, and
renting or owning and running that crane adds to the cost of the
labor.


If you time your truss delivery properly, then the delivery driver will
lift them onto the roof for you. All you need to is roll them up and
nail them down.
