Thank you. It has served me well.

I did install OSB decking, and installed some shelving supported by the vertical sections of the trusses. Some of this can be seen in the pictues. All built to help spread the load.

Before I did any of this, I asked my truss builder about it. His reply: "You can safely store bowling balls up there, as long as you don't stack them." (Obviously, this does not necessarily apply to anyone else's trusses.)
