Massive 770cc UTV with 43°F Air Conditioning! Massimo Sentinel 770 Walkaround

In this video, Collin Johnson from REV Powersports gives a full in-depth review and walkaround of the Massimo Sentinel 770 HVAC. This machine comes fully loaded from the factory with premium features, including a game-changing, completely independent rooftop air conditioning system. We left this demo unit baking out in the sun until the seats hit over 103°F, then turned on the AC to see just how fast it could cool the cab down. Check out the results below! ❄️ The Independent AC Test: The coolest feature of the Sentinel 770 is its rooftop AC system. It is powered by a dedicated 24-volt lithium battery bank mounted under the seat, giving you up to 8 hours of runtime completely independent of the engine. Even with the machine turned completely off, hitting the "Strong" button on the remote dropped the vent temperatures down to a freezing 43.5°F! 🔧 Key Specs & Features: Engine: Reliable Linhai Yamaha 770cc engine (the same power plant trusted in Yamaha, Rhinos and Grizzlies). Technology: A massive digital infotainment screen featuring wireless Apple CarPlay, built-in GPS navigation, and a integrated front/rear camera system. Audio: Two premium 6.5-inch door speakers that deliver incredible sound quality. Exterior: Street-legal package out of the box (turn signals, horn, breakaway side mirrors), full-coverage front bumper, automatic windshield wiper, and wireless synthetic rope winch. Cab Comfort: Tinted front windshield, tinted side windows, sliding back glass, and full dashboard heat vents for the winter. Utility: Premium alloy wheels, heavy-duty tree kicker running boards, a full dump bed with a tailgate, and a 2-inch receiver hitch. 💰 Pricing & Financing: The Massimo Sentinel 770 comes in at $17,999 brand new. If you are looking for a slightly smaller engine, we also carry the Sentinel 570 model for $15,999. We have excellent financing options available right now! This is our shop demo unit, so come on down to REV Powersports, take it for a spin, and experience that ice-cold AC for yourself!
