Off-grid summer camping can put both rooftop A/C units to work. This 7,500-watt diesel generator supplies onboard power for your motorhome, with sound-insulated housing and vibration mounts that keep the engine from dominating camp.
Highlights
Power Both Rooftop A/C Units: 7,500 watts supports dual cooling when total loads stay within range.
Power for Sensitive Electronics: Pure sine wave output runs appliances and devices at 120V.
Less Noise at Camp: Insulated housing, enclosed muffler, and 3-point mounts reduce noise and vibration.
Match Power to Your Needs: Load-matching operation changes engine speed as electrical demand changes.
Check the Fit Before You Swap: Published dimensions and 420-lb weight help with replacement planning.
Keep Up with Maintenance: Hour meter, self-diagnostics, and service access make checkups simpler.
Features to know about
Keep Both A/C Units Running Away from Hookups
Hot afternoons away from shore power can put both rooftop A/C units to work. With 7,500 watts at 120V and 62.5 amps, this onboard diesel generator can run 2 A/C units when their combined running and startup demands, along with the other loads, remain within its rating. It also supplies pure sine wave power for appliances and sensitive electronics.
Enjoy the Campsite, Not the Generator Noise
A diesel generator doesn't need to drown out your time outside. The sound-insulated housing encloses the cooling system and muffler, while 3-point vibration-isolation mounts reduce vibration and engine noise. Load-matching operation adjusts engine speed to what your motorhome is using instead of running at one speed regardless of demand.
Know What Fits Before Replacing Your Old Onan
If your older 7,500-watt generator has reached the end of the road, compare more than the nameplate before ordering. This QD 7500 measures 36.4" long x 24.2" wide x 22.3" tall and weighs 420 lbs. Check the mounting space, wiring, fuel connections, and exhaust routing on your motorhome. Your existing inside start switch and exhaust may be reusable, but that depends on how the original generator was installed. This model outputs 120V, so confirm the wiring and transfer-switch setup on a 50-amp coach.
Start It and Keep Tabs on Its Health
With a compatible remote control panel (sold separately), you can start and stop the generator from inside your RV, and automatic timed glow plugs take care of preheating in colder weather. An hour meter tracks use for maintenance, self-diagnostics help point you toward a problem, and the service panel keeps routine maintenance points within reach. Built-in 10-amp regulated charging also maintains the generator's starting battery.
