No worries, I know the Champ is loud. You will never see me suggest it or any other generator be run around others. By yourself out in the sticks is up to what each person can tolerate themselves. At least I can get a enclosure tent and knock the noise down to the level of a Honda Handi.
As far as solar goes, it isn't for everyone. Those it is for are the lucky ones. It doesn't have to be expensive if done right. Our panels are on 50 foot tethers so we can park where we want although at those elevations having the sun warm the trailer is a good thing most of the time. There were a few times we could have used the air for a few hours this year had we taken the Champ, as it was a few fans did the trick.
