Description

The Onan QG 4000i RV generator is ideal for light and medium-duty RV applications. This CARB 2024 certified generator set features low fuel consumption, single-side servicing, and quiet operation (63db at no load, 66db at half load). It is 13% lighter, has returnless EFI, and 25% larger oil capacity which means improved maintenance intervals. Not only does the QG 4000i allow RVers to have power wherever they go, but it also provides a peaceful, quiet journey.
