Quick Answer
The top diesel generators for RV use are those with high power-to-weight ratios, reliable fuel systems, and robust construction. Look for models with 3-10 kW outputs, 1-4 cylinder engines, and automatic or semi-automatic ignition systems. Some popular models include the Kohler 10RESV, Onan MDK, and Westinghouse WGen6000.
Key Features for RV Generators
When selecting a diesel generator for your RV, several key features should be considered. These include the power output, which should match your energy needs; the fuel consumption rate, to avoid excessive fuel costs and waste; and the overall weight and size of the generator, to ensure it fits in your RV without compromising storage space. Additionally, consider a generator with an automatic voltage regulator to maintain a stable output voltage and prevent damage to sensitive electronics.
Diesel Generator Brands for RVs
Several reputable brands specialize in diesel generators designed for RV use. Kohler, Onan, and Westinghouse are among the most popular options. Kohler’s 10RESV, for example, produces 10 kW of power, has a 1.9 L 3-cylinder diesel engine, and weighs around 220 pounds. Onan’s MDK series offers 3-6 kW outputs and features a 1.8 L 3-cylinder engine. Westinghouse’s WGen6000, meanwhile, produces 6 kW of power and has a 1.2 L 4-cylinder engine. When choosing a brand and model, research their reliability, customer support, and warranty offerings.
Maintenance and Operation Considerations
Regular maintenance is crucial to extend the lifespan of your diesel generator and ensure reliable operation. This includes checking oil levels, replacing air filters, and cleaning the spark arrestor. Additionally, consider a generator with a low-oil shutdown feature to prevent engine damage in case of low oil levels. To operate your generator efficiently, choose a location with good airflow, keep it away from flammable materials, and follow the manufacturer’s guidelines for usage and storage.
