???? For open frame Generator users.

Thanks for the replies. The reason I asked is there is a Landmark 5th wheel parked about 200 feet from me. When the couple comes home from the days sight seeing around 4pm they crank up the generator and go inside till quite time at 8 pm. They then come out sit around the campfire till late. You can hear the generator all over the CG and was wondering how the noise would be inside there RV.
