From what I read about trusses the same as mine is, this truss system is what they consider a minor span of only 24' & it would take over 500 pounds per square foot to cause that truss system to give any.
So do whatever you want to do, I know what materials & how my garage was built, I have never had a problem doing this way & will continue to do it this way until someone buys me a lift...
so if we took a 10 x 10' section in the centre of the span = 100sq' and attached 500lbs to each square ' you would stand under it
