I have prettty heavy curtains, although I could gladly add another layer. I would talk to the guy, but I have a feeling it wouldn't help. I'm sure he would have a newer vehicle if he could, and a better job if he could. And there's really not much of a parking option.
It may sound like I'm too lenient on the guy, but I would like to think he's not deliberately trying to wake people up.
I'll try some earplugs tonight and cross my fingers

I've slept in a gas mask before, so I'm sure I can sleep in ear plugs.
