My detached garage with metal siding has 2x4 trusses spaced 4 feet on

cause sagging/or other problems?

If the trusses are spaced 4' on center, you have much greater worries than
any
ceiling you might put up there. That's *much* too far apart to adequately
support the *roof*.

Did you mean 2' on center?

Its all in the truss design. My barn has trusses on 10' centers and a 50
#/sq.ft. snow load design. Way plenty to hold a ceiling too,

But knowing this guy, his building will fail with the first heavy wet snow.
maybe he lives where snow don't fall.
