Quiet power.
This Onan RV generator keeps noise and vibration to a minimum, allowing you to have a peaceful, smooth journey. Plus, its high-efficiency performance means you consume less fuel so you can stay out longer and save money.

- Automatic altitude adjustment – Exploring way above sea level? The QG 2800i will adjust to whatever level you’re at.
- Increased cargo capacity – Not only does this generator take up less space, but it’s also 9% lighter than previous models.
- No alternative fuel tanks necessary – The QG 2800i is available in gas or LP (propane).
- Reduced noise, vibration and fuel consumption – All thanks to the variable speed PMA technology.

Our warranty philosophy
Cummins’ guiding principle when it comes to warranties is simple: we agree to pay to fix any part that has failed due to a defect in Cummins materials or factory workmanship.
For RV generators used in an RV application, this means you’re protected three years from the warranty start date, or 2,000 hours, whichever comes first. For RV generators used in non-RV applications, the warranty coverage period is one year from the warranty start date, or 1,000 hours, whichever comes first. Extended warranty coverage is also available for purchase and covers you for five years from the warranty start date, or 3,000 hours, whichever comes first.
