Class A Motorhome Slideout Onan Diesel

Generators for RVs bring all the conveniences of home out on the open road with power for air conditioners, refrigerators, televisions and other small appliances and lights. They are engineered and built specifically for recreational vehicle types that include Class A, B, and C motor homes, diesel pushers, fifth wheels, and other recreational vehicles and trailer applications.

Norwall PowerSystems offers generators from Cummins Onan in different sizes to meet a wide range of power requirements with models that run on LP gas, gasoline, and diesel fuel. When used in an RV, the generators carry a three-year, limited consumer warranty.

In motor homes and truck campers, RV generators operate off the vehicle’s fuel tank. In trailer applications, they use on-board propane or gasoline tanks. Either way, an RV generator brings comfort and convenience to on and off road adventures.

A gasoline powered RV generator can run off the vehicle’s fuel tank. All models meet California and U.S. EPA Emissions Requirements.

The Quiet Gas line of gasoline-powered generators from Cummins Onan supply 2800 to 7000 watts of power. They feature microprocessor controls that include diagnostics, overhead valve engines, a fully enclosed design and muffler, and smooth, quiet operation. Models with the EVAP specification meet CARB III and EPA phase 3 standards.

The 2800 and 4000 watt models will start and run one, 13,500 BTU air conditioner with power left over for lights and other needs, while the 5500 and 7000 watts units will handle two air conditioners.

The sound-reducing case encloses the muffler and cooling system to dampen noise and the three-point mounting system reduces vibration. Other features include a USDA approved spark arrestor, hour meter, and electric fuel pump. Safeties protect the units from over-voltage, low oil pressure, high temperature, overloading and over speed conditions. These generators meet EPA and CARB emissions standards.

The 8000 watt units can handle two, 15,000 BTU air conditioners with more than 3000 watts of power left over for other uses. Larger 10,000 and 12,000 watt generators will handle three rooftop air conditioning units while supplying an additional 3000 to 4000 watts of power.

Operation of these generators is ultra-smooth and quiet―67dB at ten feet for the 5500 watt and 6500 watt models, and 70db for the 2500. All the RV generators meet or exceed US Park Service regulations for a noise level of 60dB or less at 50 feet. Sound levels are further lowered once the unit is installed in the vehicle or trailer.

The 2500 and 3600 watt models will each run a single, 13,500 BTU air conditioner with some power left over for other appliances. The 5500 and 6500 watt units will start and run two AC units. LP gas powered generators are well suited for travel trailers, sport-utility trailers, horse trailers, and pop-up campers.
