I got this at costco. home depot has it in camo for $600.
PowerStroke 1,700W Running/2,100W Peak Inverter Generator
As for how loud... many factors contgribute to that - load being one. Another is where it's positioned - 35' away from your camper in a forest? Not an issue. Under your bedroom window with another camper 10' away? They're all gonna be annoying from the reflected sound.
Listed (on home depot site) at 63db 'operational'...so I assume under a load.
Can't be run in parallel if that's an issue.
Has a 12v outlet and comes with cord/clips to charge a battery. Handy.
