How Many Miles Per Gallon Does A Diesel Motorhome Get?

A diesel pusher is the way to go if you want the benefits of a Class A motorhome with slightly better fuel economy (plus a smoother ride and higher-end equipment in general). A diesel engine is slightly more fuel efficient than a gas engine, though not by much. A Class A diesel pusher should get between 7 and 12 mpg on average, depending on size and weight.

How many miles will a diesel RV last?

If the maintenance and driving conditions are appropriate, a diesel RV will last on average 300,000 miles. Despite this, if the motorhome has been mistreated, the engine is unlikely to go beyond 125,000 miles.

Over time and miles, you will notice the engine wear, which will cause it to start a bit worse, increase its consumption, or leak more and more gases to the outside.

How many miles will a gas motorhome last?

Standard gas engines, on the other hand, have a limited lifespan of roughly 200,000 miles if properly maintained. Because of the need for compression, gasoline engines wear out more quickly and so have a shorter usable life.

What kind of mileage do diesel motorhomes get?

MPG – While large motorhomes consume a lot of fuel, diesel engines are more fuel efficient than gasoline RVs. This increased efficiency may be able to partially offset the expense of diesel fuel. A gas motorhome should get you 6-10 miles per gallon, while a diesel RV should earn you 8-14 miles per gallon.

Is it worth buying a diesel motorhome?

A gasoline-powered RV and a diesel-powered RV have a few important characteristics. The most obvious distinction is that a gasoline-powered RV runs on, well, gasoline. What about a diesel RV? You guessed correctly. It is diesel-powered. But, as you might think, there are a number of other distinctions between the two.

The price gap between diesel RVs and their gasoline-powered counterparts, according to RV Life, is the second biggest difference. Diesel RVs are often more expensive, according to RV Life. However, RV Life points out that for the extra money, you receive a vehicle with a considerably longer lifespan and a greater resale value.

There’s also a difference in terms of capability and power. You should anticipate a diesel RV to maintain its pace during a climb better than a gas RV because diesel engines have higher torque. A diesel RV should also be more fuel efficient than a gas-powered RV.

What is high mileage for a diesel engine?

Of course, there are exceptions to every rule, but these vehicles aren’t worth the risk. If you absolutely must have a high-mileage vehicle, go for the petrol model with the largest engine.

A smaller engine will be pushed to 90% of its capacity under the same driving conditions, whereas a larger engine will cruise at 70%. Less stress equals fewer repairs.

“Is automobile age or miles more important?” I’m regularly questioned when it comes to older vehicles. When compared to a newer car, an older car always wins – which makes obvious when you think about it…

How much does it cost to fill up a diesel RV?

Class A motorhomes are the largest (21′-40′ long) and frequently the most luxurious; Class B motorhomes are the smallest (16′-26′); and Class C motorhomes are mid-sized (20′-32) and usually have a bed over the driver’s cab.

  • A basic Class A motorhome, which resembles a bus or semi-truck, costs $50,000 to $100,000. Upgraded models with features like a slide-out, a rear camera to make backing up easier, or luxurious dcor can cost between $200,000 and $500,000. Options such as multiple hard-sided slideouts, an entertainment center, and a gas fireplace can range from $500,000 to $800,000. Diesel engines are more expensive than gas engines, and diesel-pusher RVs (those with the engine at the back) are more expensive than front-engine motorhomes.
  • Camper Vans, also known as Class B motorhomes, range in price from $40,000 to $80,000 for a basic model to $90,000 to $125,000 or more for a luxury model. They have the appearance of a conventional van and are typically 15′ to 26′ length.
  • Class C motorhomes, sometimes known as mini-motorhomes or mini-RVs, range in price from $50,000 to $80,000, depending on size (usually 16′-26′) and extras. More deluxe Class Cs (up to 36 feet long, on a heavy-duty van or truck chassis) can cost $85,000 to $140,000 and include amenities like a larger bathroom, full-sized appliances, and a home theater system.
  • Motorhomes depreciate as soon as they leave the dealership, so a well-maintained motorhome a few years old can be 20% to 30% less than the initial purchase price.
  • A motorhome must have at least one bed, a table, a cooking area, and storage space. A dining table and benches can be converted into a bed in smaller versions, while bigger motorhomes may feature a separate bedroom with a queen- or king-size bed.
  • With a normal gasoline tank holding 100-150 gallons, Class As average roughly 8-10 miles per gallon. A fill-up may cost $250-$600 and last 800-1,500 miles at $2.50-$4 per gallon. Class B Camper Vans earn 10-25 mpg depending on make and model, engine size, vehicle weight, city or highway miles, and speed travelled, and are similar to a conventional family van. With gasoline tanks holding 25-55 gallons, Class C motorhomes average 10 mpg; a fill-up may cost $60-$220 and last for 250-550 miles at $2.50-$4 a gallon.
  • Campground or RV park costs range from $10 to $50 per car per night, depending on the location’s appeal, if the site offers utility hookups (electric, sewer, and water), and other facilities.
  • Shop around for RV insurance quotes before purchasing an RV; premium costs vary greatly. The cost of vehicle registration varies by state, but it normally ranges from $50 to $400 per year.
  • Tires, brakes, and filters will all wear down in exact proportion to the amount of miles driven. Some Class A motorhome owners recommend setting aside $3,000-$5,000 per year for upkeep and repairs, especially if you live in your RV full-time.
  • Renting an RV storage space can cost anywhere from $20 to $100 per month outside and $45 to 450 per month within. A Class A motorhome may be rented for $1,400 to $3,500 for a seven-day, 700-mile trip, while a Class C can be rented for $1,000 to $2,500 for seven nights and up to 700 miles.
  • RV events bring together a wide range of makes and types at one location; admission can be free or $5-$10.
  • The majority of dealer prices can be negotiated. RV buyers and owners describe buying a new Class A motorhome for 25% or more less than the manufacturer’s suggested retail price on message boards provided by Woodall’s and MotorHome Magazine.


For many people looking for a new motorhome, the price is the most important factor. What is the cost of a motor coach? When purchasing a motorhome for the first time, many people choose for a gas model rather than a diesel or a luxury coach.

Within a category, there are, of course, different levels of quality. The top gas motorhomes on the market compete with some lower-quality diesel vehicles, depending on what you’re searching for. Between the best luxury diesel motor coaches and the most basic gas recreational vehicles, there is a significant and apparent difference.

However, if you want to save money while still getting a great coach, you’ll probably want to go with a higher-end gas model. You won’t regret investing extra money on a luxury diesel coach if you’ve been saving for retirement to become a full-time RVer. Diesel coaches also have a higher resale value than gas motorhomes.

Fuel Efficiency

When comparing the fuel efficiency of a diesel vs. a gas motorhome, diesel motorhomes are far more efficient. This is mainly due to the fact that diesel fuel has a higher energy value than gasoline. Diesel fuel can provide up to 10% better fuel economy by volume due to its higher energy density.

Maximizing engine power and efficiency is a major concern for recreational vehicle owners. Because strong motorhome engines take so much fuel on a cross-country trip or while driving across terrain, owners want to be sure they are getting the most out of their fuel consumption. While diesel fuel is more expensive than gasoline, depending on the type, driving a diesel coach can save money in the long run due to increased fuel economy.

So, if you plan on putting a lot of miles on your motorhome, driving it across the country and living in it full-time, a diesel motorhome is the way to go. However, if you’re just going on vacation and want to try out the recreational vehicle lifestyle, a gas engine motorhome is probably the better option.

Comfort and Luxury

When shopping for a motorhome, it’s natural to concentrate on the most important aspects. What kind of chassis does the coach have? Is there enough power in the engine? Is the value I’m looking for being delivered at the proper price?

One thing you could overlook is the interior’s level of comfort. Many people find it difficult to concentrate on the intricacies until they have moved into their coach. They believe they’ve spent enough time inspecting the electronics, bedroom, bathroom, and kitchen. However, after they have the coach, they discover it does not feel like home in the way they had hoped.

A gas motorhome, on the other hand, will likely offer less comfort and more minor problems — flaws that you won’t notice until you spend a significant amount of time in the coach. Diesel motor coaches typically have nicer interiors and better components, which is more significant to a full-time RV owner than it is to someone who is just starting out in the RV lifestyle.

How long is a diesel pusher motorhome?

Diesel Pusher motorhomes are a subcategory of Class A RVs. Diesel pushers differ from other Class A RVs in that they feature a diesel engine while the others have a gas engine. Diesel pushers can be up to 45 feet long in general. They usually have the widest windows of any model, allowing for improved sight while driving. They normally sleep 2 to 4 people and have a lot of storage space. The diesel pusher’s shape is comparable to that of a bus, making it easier to maneuver than a standard front-wheel drive vehicle.

How many miles per gallon does a 454 get?

The Chevy 454 was initially introduced in the 1970s. The 454 is a carbureted big-block engine seen in many older Chevrolet automobiles and trucks. To deliver high-end torque and speeds, the engine has eight cylinders. Because of the bigger bore and eight cylinders, the gas mileage is quite low. The engine gets 10 to 15 miles per gallon on average. Increasing gas mileage without losing vehicle performance involves only a few affordable and simple engine tweaks.

What is high mileage for a diesel pusher?

This is highly reliant on how well you and the previous owner care for the RV. If an owner has maintained a maintenance program and serviced their RV on a regular basis, it will last considerably longer than if they have neglected their vehicle.

RV engines are designed to endure between 200,000 and 300,000 miles on average. Motorhomes with diesel engines, once again, can last much longer.

However, once your RV reaches 200,000 miles, you may expect to have to pay for some major repairs. To avoid future difficulties, a mechanic may want to replace the timing belt.

Once the RV reaches 200,000 miles, the owner may need to consider brake and transmission repairs. If you’re seeking to buy an RV, you should steer clear of anything with more than 200,000 miles on it. In the near future, several big repairs will be required.
