I posted a rant after our last camping about a site that had a generator running from 7AM until 10pm... technically legal, but why go to a primitive campground during fall
use my Harbor Freight floor mats to do this.
You're not going to quiet a Honda down much.
The generator manual should have specs on the nearest wall clearance and ventilation specs.I used a generator in a wooden box with the front completely open. The box had vents on the side and ventilation at the roof. I turned the exhaust toward the open side. (I was protecting from rain). The next time I used the generator, it quit making power. It might be a coincidence or not...I believe it overheated in that box.
