At 9-10,000 ft Big red is going to be running balls to the wall and that uses a lot of gas and will be as loud as it can be.
Couldn't tell you that high because I live in Idaho, but I can tell you that at 7-8 thousand feet, my Honda 3k does not run balls to the wall or even close to it. As said before, it is quieter than the 2k Honda.
The thing here is, I own a small champion and it's a good generator but it's not a Honda.I own a Springfield trailer, a great trailer but it is not a Jayco either,having owned a couple.
I love the entry level talk, trailers are entry level but generators:B
