We would like to take down a wall that runs in the center and the length of my small bungalow.

We have a crawl space. There are two cinder block posts on cement pads in the crawl space. They are both spread apart from one another and in the middle of the crawl space and positioned lengthwise to the house. Does this mean the wall is necessary?

The house is about 24' wide.

I have a picture of the truss but can't post here. They are 2x6, and 2x4 at the smaller edge (I think that's called the knee wall??.

Thoughts? I've read a lot about truss and load bearing and am somewhat confused...

Thanks,
J.
