Enjoy reliable comfort wherever you stop. The QG 7000i powers two AC units, protects sensitive electronics, and runs on gas or propane, giving you the freedom to travel longer, stay cooler, and worry less about hookups.
Large rigs put real demands on a generator, especially when it's hot and both air conditioners are running. The QG 7000i Dual Fuel is built for those moments, with enough output to handle two 15,000 BTU AC units plus your everyday base load, even in 100°F heat. Instead of running at full throttle all the time, the engine automatically adjusts to what you're using. That means it runs quieter, uses less fuel, and sends less vibration through your coach compared to older fixed-speed generators.
This dual fuel EFI inverter model replaces earlier onboard generator designs, but the layout has changed. The exhaust and fuel ports are positioned on opposite sides compared to previous Onan models. Even if the overall footprint is similar, existing intake, exhaust, and drain openings in your generator bay will not line up. Plan for adjustments to venting, fuel routing, or mounting cutouts during installation. As with most onboard generators, working with an experienced installer can help ensure everything is set up correctly the first time. You can use etrailer's installer locator to find a qualified shop near you and get help with install.
With inverter-based electrical output and a Permanent Magnet Alternator, your RV receives stable, high-quality power for everything from induction cooktops to laptops. The consistent voltage helps protect sensitive electronics from surges and fluctuations so there are no flickering lights or unexpected voltage dips. If your rig runs an inverter/charger and lithium battery bank, this steady AC output also supports reliable charging without nuisance faults or power rejection. And because the EFI system automatically adjusts fueling based on load and conditions, performance stays consistent at higher elevations and in extreme heat.
This generator is built to fade into the background once it's running. The fully enclosed design and catalytic muffler help keep noise low, while vibration-isolating mounts reduce shaking and rumble inside your coach. That means quieter mornings, calmer evenings, and less disturbance to nearby campers. It's designed to meet noise limitations in national parks and campgrounds, letting you settle in without drawing unwanted attention or complaints.
RV builds don't all look the same, and fuel choices often come down to how and where you travel. This generator gives you the freedom to run on gasoline or propane, so it can match your setup instead of forcing changes. Switching fuels is handled automatically by the onboard electronic controls, and the EFI (electronic fuel injection) system eliminates the need for a gasoline return line, simplifying installation. That makes the QG 7000i a smart fit for new builds and a practical upgrade for older coaches that weren't originally designed for dual fuel.
The QG 7000i is built for the way RVs are actually used, not just how they look on paper. Routine checks and service are simpler thanks to single-side access, and extended self-diagnostics help pinpoint issues faster when something needs attention. J1939 communication allows the generator to integrate with modern RV systems, making monitoring and troubleshooting more straightforward. One-touch electric start makes it easy to fire up at the generator, and a sealed remote connector allows interior start/stop capability when paired with a compatible remote switch (not included). And because it's the lightest installed 7,000-watt generator available, it reduces strain during installation and adds less weight to your RV over the long haul.
For many RV owners, an onboard generator quickly becomes something they rely on every trip. It allows you to manage heat, power appliances, and stay comfortable without planning around hookups. That kind of reliability matters more the longer you own your RV. If you're replacing an older unit, upgrading to more power, or adding an onboard generator for the first time, the QG 7000i supports travel that's less restricted by weather, location, or campground availability. It's an upgrade that continues to pay off over years of use.

Hi everyone. Steven here with etrailer. Today we're taking a look at our Cummins Onan Qg 7,000 I onboard RV generator folks. Again, 7,000 watts of power dual fuel and a built-in inverter that is carb compliant. Folks, this is a great option for you. It is a direct replacement sized to fit your existing generator bay.
So as far as the mounting it and fitting and all that, you really shouldn't have to do anything different on that providing you get the same size again, 7,000 watts, maybe you're actually upgrading from maybe a 5K or something smaller. Most of these are the same, but I do wanna start off with you giving dimensions, make sure it's gonna fit your generator bay. So 33 and five eighth inches overall on a length from the side 22 and one eighth inches deep and a height 16 and three quarter inches tall. Now it does come with this little filter and some screws for installing that. You can check out the instructions to decide or rather show you exactly where that goes.
I do want to go ahead and spin this around before I take the cover off just so you can kind of get a look at everything. Keep in mind this wire here as I'm spinning, that would come through the side panel there obviously, and it would be hooked up exactly where it needs to go professionally if you're not doing it yourself. And as you can see, not much to it. Just a nice hard green shell. I'm gonna step around and come to the front.
Now, when this is installed, when you need to access just the normal everyday operation stuff, you simply twist these two keepers. It does have a little force to it, so when you get that loose, just kind of pop it out. Like I said, you may have to pull a little hard there to get that to come out. And then you have your case access panel there, rather in the front. Now you can get access to your oil, the fuel things, the better hookups you have your wires here that again, should be plugging in directly to your setup that's already existing there on your camper RV or wherever you got this installed.
And then of course, your main switches and stuff. I did have to pull out one, two, three, four bolts out of the side. Two from each side here. So bear with me while I go ahead and get this cover popped off here. And again, most of the time you're probably not taking off this case cover unless it's being maintenance done on it or those kind of things. And again, that's just a hard plastic or what I would say fiberglass probably shell. Bear with me while I set that off to the side. Okay, so woo. Now we can see pretty much inside, we can see the guts, we can see the main motor assembly, the generator, the muffler and everything. Just rest assured folks, there's a lot of information on this. I'm just kind of giving you a quick overview. Excuse me there, so again, your muffler, everything here has been made and certified in all 50 states. You can operate anywhere, national parks, those kind of things. It does meet all those regulations for national parks as far as the fire regulations, noise levels, all those kind of things. And again, you can check out all those options on the product page itself if you need to get all those individual specs. We're not going over all those things today. I really just wanna give you an inside overview of the generator. Again, you got the battery side and then I'm gonna let that wire hang. I do wanna throw up an image. I don't have access to it to show you really good here. I do wanna show you an image here of the other hookups that are on here and everything as well. Keep in mind this has built-in suspension, if you will. So it has isolators underneath the engine in different spots. So that's gonna keep that vibration and everything and the noise level down. Again, most of the time you're not taking off this cover unless someone's doing some kind of maintenance, whether it's changing out a starter, maybe doing those kind of things. Even all your general maintenance, like your oil flush and change, those kind of things. There are holes down in here and there's an on off knob back in here where you can drain the fluids and stuff. And then again, of course we have our oil dipstick and everything. You just simply twist it out. And now we could check our engine oil depths and all that. And yes, there is oil in it from the factory. I'm dripping in here. I'll have to clean that up here in a second. But again, you can access everything here. Once again, all your plugins, your main on and off circuit breaker, those kind of things. So again, folks, a great option for you. Again, dual fuel. This is a great option for you. Modern EFI engine and inverter design. So it's very proficient. 15,000 BTUs is what this can handle. Two of those AC units. So this will give you more than enough power probably for off-grid application on your RVs, maybe campers, those kind of things as well. So again, gasoline or propane, it's easy to use. You have onboard switching. This is the Cummins Onan QG 7,000 I. I'm Steven with etrailer. Thanks so much for watching. As always, reach out if you have any other questions and have a good one.
