A common question we receive at Lichtsinn RV is “Should I buy a Class A gasoline powered coach or a Class A diesel pusher?”

Winnebago Class A Diesel vs. Gas

Below we break down the two options and included common questions that  guests ask when deciding between a Class A Gas or Diesel RV.

Winnebago Class A Diesel models include the Winnebago Forza and the Winnebago Journey. The Forza is built on the Freightliner XCS Chassis and provides a comfortable environment and adaptable sleeping and seating spaces in its 3 available floorplans. The Journey is built on the versatile Freightliner Maxum II XCM Chassis and is designed for luxury travel and entertaining. Each of the Journey’s 3 floorplans are fully loaded and feature stylish modern refinements from front to back.

Winnebago Class A gas models include the Winnebago Vista, Winnebago Sunstar and the Winnebago Adventurer. These models are built on the Ford F53 chassis. The Vista and Sunstar are available in 5 floorplans and feature Winnebago quality with affordable living. The Winnebago Adventurer is Winnebago’s premier Class A Gas coach and has many luxury features and ample storage with its 5 family friendly floorplans.

A Class A Diesel Pusher includes the following features compared to Class A Gas:

  1. Increased torque or power.   Winnebago diesel pushers range in torque from 700 – 1,150 lbs ft of torque or power, compared to approximately 460 lb ft in Ford Class A gasoline powered coach. 
  2. Increased towing capacity. A Winnebago Class A Gas chassis has a towing capacity of 5,000 lbs.  Winnebago diesel pushers have a towing capacity of 10,000 lbs.
  3. Comfortable ride. Diesel Pushers include a more comfortable ride with air ride suspension and air braking capability.
  4. Quiet ride. Diesel Pushers provide a quiet ride, which stems from the fact that in a Class A diesel pusher the engine is located in the rear of the coach, nearly 30-40 feet behind the cab area.  In a Class A gas coach the engine is located in the cab area. However, the Class A Gas Ford chassis has evolved its five speed Torqshift transmission allowing for shifting at lower RPM points. This drives down engine noise compared to previous powertrains. 
  5. Resale value. Resale value of a diesel pusher is typically stronger than a Class A gasoline powered coach. The difference in resale value is due to Class A diesels tending to last longer than Class A gas RVs. There’s a reason transportation / delivery type vehicles are diesel and that’s because the engines can run for hundreds of thousands of miles. 

Price is probably the first factor that people notice when comparing Class A Diesel to Class A Gas. The Winnebago Vista and Sunstar MSRP starts at $176,822, the Winnebago Adventurer MSRP starts at $201,769, the Winnebago Forza MSRP starts at $329,028 and the Winnebago Journey MSRP starts at $439,476. The MSRP does vary by model based on floorplan and options selected. A main component of this cost is the chassis the RV sits upon. Price is a large consideration when determining Class A diesel vs. Class A Gas. 

Another consideration as you decide Class A Diesel vs. Class A Gas will be maintenance and operating costs. Typically gas coaches are less expensive to service and maintain. Many “do-it-yourselfers” might take on service projects with a gas coach but when you have a diesel, it’s more likely you’ll seek out a diesel mechanic for your service. Freightliner repair facilities aren’t as frequently located to service your diesel chassis compared to the many Ford locations for servicing your gas coach chassis.

Class A diesel pusher motorhomes come with air braking that is used in conjunction with engine and transmission grade braking, which is more reliable and will stop a heavy vehicle more quickly than standard hydraulic disc brakes that come with Class A gas motorhomes.  Engine and transmission braking also allow for steady use of cruise control in high grade areas to provide consistent traveling speeds up and down mountains.

All diesel coaches are required to use DEF which allows the coach to burn fuel cleaner. Gas coaches are not required to have this. This was mandated in 2010 so you will see it in diesel coaches that are 2011 or newer. DEF tanks range in size with most being around 13 gallons in a Class A diesel RV. The typical RV’er travels about  between 5,000-9,000 miles per year and one gallon of DEF typically lasts between 300-500 miles.  So depending how far your travels take you, you may have to refill your DEF tank between 1-3 times a year. You don’t need to fill your DEF tank every time you fill the gas tank. Many diesel truck stops have DEF at their dispense stations and the tank is easily accessible on the coach. 

Fuel efficiency is similar averaging 7-10 mpg on either the gas or diesel options. Dual fuel fill is available in the diesel pusher models. Gas is only available on one side and  location of fill varies depending on model.

If you have height limitations for your RV due to a storage garage size, diesel pushers allow you to drop the air allowing you an additional 2-4” which may allow you the clearance you need to make it under the garage door. The Vista and Sunstar are between 12’3″ and 12’4″ in height, the Adventurer 12’4″ to 12’6″, the Forza 12′ and the Winnebago Journey 13’3″ in height. The height of each model is measured to the top of the tallest standard feature and is based on the curb weight of a typically equipped RV. 

A further determination in deciding gas vs. diesel is how much storage capacity do you need? This will also effect the ride of your coach and is included in the GVWR (Gross Vehicle Weight Rating.) The GVWR is the maximum amount of weight that your RV can handle safely. This includes your unloaded vehicle weight rating plus the occupant and cargo carrying capacity.  Gas GVWR ranges from 18,000 lbs to 22,000 lbs. In a diesel pusher GVWR will range from 26,000 lbs to 38,700 lbs. The tires will also effect the ride of the coach. Winnebago Class a Gas models have either 19.5 or 22.5” tires. Winnebago Diesel Pushers all have 22.5” tires.

Exterior storage in Class A Gas vs. Diesel models is significantly different as well. You’ll find a substantial amount more storage in diesel pushers primarily due to Freightliner XCS chassis found on the Forza and the Freightliner XCM modular rail bridge chassis of the Journey.

Maintenance and Operating Costs

  • Beyond purchase price, the overall maintenance and operating expense of a gas coach is generally less expensive than that of a diesel. However, you may do less maintenance overall with a diesel pusher.
  • Cost of parts and service work in a gas powered coach is less as the coach is less complex.
  • It can also be more convenient to find service locations for your Class A gas Ford chassis vs. the Class A diesel Freightliner Chassis. 

Fuel Considerations

  • Cost of diesel fuel is generally higher than that of gasoline.
  • MPG — should expect average of 7-10 with either gas or diesel powered Class A’s. 
  • Class A Gas Fuel Fill – 80 Gallons, single location located in a different location dependent on floorplan.
  • Class A Diesel Fuel Fill – 90 to 100 Gallons, Dual Fuel Fill located on each side of the cab area. 

Engine Longevity

  • Class A Gas – Ford 7.3L V8
  • Class A Diesel – Forza | Cummins 6.7L ISB, Journey | Cummins 8.9L ISL
  • Because diesel engines run at lower RPMs than gas, there is less strain on the engine.
  • Diesel engines are designed to run hundreds of thousands of miles.

Horsepower

  • Gas: 350
  • Diesel: 340 Forza | 380 Journey

Torque

  • Gas: Approximately 460
  • Diesel: 700-1,150

  • Gas: Torqshift 6 speed automatic transmission with tow/haul mode
  • Diesel: Forza | 2100 or 2500 6-speed automatic (dependent on floorplan,) Journey | Allison 3000 6-speed automatic 

Towing Capacity

  • Gas: 5,000
  • Diesel: 10,000

Generator

  • Gas powered: Vista/Sunstar | 4-5,500-watt, Adventurer | 5,500-watt
  • Diesel powered: Forza | 6,000-watt, Journey | 8-10,000-watt

As you can see, there are many considerations as you determine if a gas or diesel powered Class A RV is right for you. Contact a Lichtsinn RV consultant to find out more about Winnebago Class A Motorhomes.
