OMFG. Tell me you did not just say that...

The concern is the DRYWALL, not the trusses.

When they drywalled the addition on my parents' house back in 1991,
the ceiling sagged between the trusses, and they were on 16"
centers!!!

Can you imagine hanging a drywall ceiling from trusses on 48" centers?
The ceiling would look like an inverted ski mogul hill after about 24
hours.
