I have about 20 hrs of run time on these. There super quiet like the Honda’s. You can run one by itself or both together. They ran my camper ac microwave at the same time without any issues. Have an eco mode as well. Asking 700 plus the ride. I’m at work so these are stock photos but the ones I have are the black and gray. I just changed the oil in them as well. Also there is a port for d c to charge batteries.
