Your concerns are something anyone considering this should keep in mind.Thumbs up @ShadowsPapa for considering this. Just making sure an unsuspecting DIYer Doesn’t start hanging and imposing rotational forces on long span prefab trusses that aren’t made to carry load. The JT hardtop is much lighter than the JLU, JkU and other tops. Typically bottom truss bottom chords are designed to hang about 5lbs/sf.
Free standing trusses up there, the bottom runs from wall to wall, don't have a lot of stability on their own.
I'd not hang anything heavier, and in fact, I am still going through things up overhead and getting rid of things - especially things of iron or if they are heavy for me to lift on a ladder, they are too heavy to be up there.
Yeah, the other roofs have more glass and indeed are heavier!
The main garage without the addition is 27x27 so it's got quite a span wall to wall where I've been working. It was interesting to see that the builder, the prior owner, had added those vertical pieces to connect the bottom cords that span the walls up to the "rafter" area above. I'm guess he was thinking of this sort of thing as like I said, he added those where he had his metal stored up there.
This is actually prompting me to do more cleaning out up there as most of what's up there has been there over 20 years - time to clear it all out and lighten the load even more!
