You certainly can apply load, it’s just not intended. The trusses form triangles so the snow load and wind uplift are actually causing tension and compression along the length of that bottom chord of the truss. Either pushing or pulling along the length based on the downward or upward pressure. That’s how they can get away with using a “little” 2x4. It’s not direct downward pressure like you get on a 2x8 or 2x10 floor joist (that is just a straight across board and no diagonals) from a load standing on top of it.

Got it. Thanks for your thoughts on this.

Based on the comments in this thread and after confirming the type of roof I have, I gave up going ahead with this idea. It might be able to support it ok but I do not want to find out.

By the way, the plan was to hang a Hammock Chair like this which would not be bearing the load 24x7.
