The typical gas mileage of the Fleetwood Pace Arrow recreational vehicle averages between 6 and 7 miles per gallon. In 2005, test drives of a new Pace Arrow 36D in Southern California and Nevada yielded 5.8 miles per gallon the first time and 6.5 miles per gallon the second time.
Fuel economy improves as the recreational vehicle mileage increases. The Fleetwood test vehicle started with 2,000 on its odometer, was equipped with standard load range G tires and carried a full 75-gallon gas tank. The vehicle weighed 20,200 pounds with its gas and water tanks full and had a 1,800-pound cargo capacity. An 8.1-liter, 340-horsepower V-8 engine and a five-speed automatic transmission with overdrive provided power for the motor home.
