Ok, I figured it out!
You can't crop any smaller than what you had showing on the sketchup screen. So even though you zoom out and it looks like alot of nothing, sketchup is putting something there. So that pdf I posted above, you can't crop. But this one you can. But still, only like I had it on the screen with the white space on the right and left side. I also verified this with another program called soPdf. I've posted it below, if anyone wants it. I've repackaged it to save you time. And it doesn't need the ghostscript or .net.
