I updated the post with a photo. From my uneducated opinion it looks like I'm SOL until I hire an engineer. At least I have a bigger door opening though and found a dead bird and a hole to the outside of the house on the right side...

Updated post with 2 more photos. Yes, the angle in the center of the first picture is the roofline. So you are saying it's structural?

Thanks, I'll give it a shot and use the recip saw trick to see if it binds. But I'm most likely ok!

The sliding door is inside the wall to the left, in the first photo, behind the orange mountain photo. As for trusses, it's an a-frame and the ridgeline is perpendicular to that wall I want to remove
