Finally broke down and bought an iq3500W gen. It was long overdue as we have in the past stayed home when dry camping. 90*-100* in a 5th wheel or TT without air is brutal. Even though here in Oregon it cools down a fair amount at night it was getting old for us oldies having to shower or do some light cooking inside the trailer when the inside is as hot or hotter than it is outside.
Really impressed with the gen. I got a sound meter app for my phone and @34' the gen is 62db on eco and with the 13,500 AC running it's the same exact 62+/-db's.
It barely revs up when the Ac's turned on.
