Like new GP6500 with CO sense (carbon monoxide shut down sensor.) Only 140 hours operation, I bought this portable during ice storm of 2025 for $950 at ACE. later equipped my house with 22,000 watt Generac. Stored inside, very clean, starts easily. Four 120v outlets, one 240/120 outslet. 8150 watts at startup, 6500 watts continuous.
