I've owned the Honda EU6500 over 10yrs now. It's now a EU7000 and has EFI. I'd like to upgrade to that as the only issue I've had is getting the carb rebuilt a few times due to crap gas.
Lost power last year for 6 days. It ran nonstop the entire time. Powered my whole house (obviously not everything at the same time). We could run all the small stuff like TVs, computers, wifi, ceiling fans, lights, fridge... basically almost anything 120v and then one major appliance (water heater, AC, Range, Oven, etc... all at same time. The thing never skipped a beat. I've even charged my Tesla with it.
On top of all that it's super quiet. Built for RV use.
HIGHLY recommend!
