And Len, just to be clear, I think we are all on the same page -- the goal is a quieter generator, whether we are in a campground or in the middle of nowhere. Assuming one has to use a generator (and there are rare times when we do), the best solution would be a really good box, like the one SoundGuy has posted about.
But there is an old saying -- the best is the enemy of the good. If one lacks the skills to make that box or can't transport it, then maybe there is a less-than-perfect solution (sheets of plywood??) that would make things a little better than nothing at all.
So that is what I am hoping to find, through trial and error and prayer. Maybe there is a half-baked technique available, one that I would actually use in the real world.
Or maybe there isn't.
