How Much Do Motorhomes Weight? Average & Examples

Have you ever wondering how much a motorhome weighs? If you’re planning on purchasing a motorhome, you want to ensure it has the features you want, including making sure it’s within the weight range you want as well. The weight of your motorhome can end up affecting how much gas mileage you get.

Here are the motorhome weight ranges:

  • A Class A motorhome that is bus-shaped weighs between 16,000 and 30,000lbs
  • A Class B motorhome that is a van-type weighs between 4,000 and 14,000lbs
  • A Class C motorhome that is larger than Class B’s weighs between 12,000 and 20,000lbs.

 When determining which type of motorhome is right for you, it’s always important to do a test run. Don’t take on a motorhome that is too large that you may not be able to handle. Not everyone can drive a top weight Class A motorhome. Some may need to go lower with a Class B.

If you’re not very familiar with the different classes of motorhomes that there are, making sure you do enough research before purchasing is important. Always keep a mind that there is a limit to how much a motorhome weighs and how much they can accommodate. As you read further on, you’ll learn about dry weight and full weight.

Dry Weight Vs. Full Weight

When calculating dry weight, do not include the weight of passengers, consumables, or any cargo. Empty tanks are the best way to calculate the dry weight. Once those tanks are filled up with water, that’s more weight that is added to your motorhome. This occurs even before it is loaded with any passengers or gear.

Dry weight is the exact weight of the motorhome that includes its standard equipment. This weight doesn’t include fuel, extra cargo, passenger weight, or any other equipment that is optional. Dry weight typically includes equipment that is commonly ordered, generator fluid and other equipment on board, and may or may not include motorhome batteries. Make sure that you are paying to how the manufacturer of your motorhome calculates your dry weight because they could be including other added things.

Full weight is the total weight of your motorhome that includes passengers, equipment, fuel, and other fluids. If you are living in your motorhome, and not towing anything extra, then the full weight is the total weight of your motorhome and everything else in it. The full weight is important because, without these calculations, you can’t evaluate if you are in the weight range provided by the manufacturer.

Full weights are often difficult to modify, but it’s easy to adjust the cargo amount that you’re carrying or reduce the fluids. The full weight is a fixed amount, and there are barriers that are short of making modifications. Some people have consulted their attorneys before making a motorhome purchase. They have been advised that if you exceed the recommended weight for your motorhome, it’s considered negligence and a lawsuit waiting to happen.

How Much Does A Class C Motorhome Weigh?

Class C motorhomes are a more compact version of the Class A models. Class C is one of the most popular choices because it has more of a natural driving feel than other larger vehicles. These types of mini-motorhomes are perfect that are new to the motorhome lifestyle.

Manufacturers are trying to improve their Class C models every year by jumping up to larger Ford and Chevy models. The larger models are diesel-powered and can pull a heavier load. They are also more fuel-efficient and would benefit the owner.

Why Chose A Class C Motorhome?

Class C has many more benefits than Class A and Class B models. Class C’s also have enough space that they can fit up to 7 people and are even easier to park and drive. Some of the other benefits include:

  • Larger sleeping accommodations
  • Easier to navigate
  • Easier to drive in tougher weather conditions
  • Less space needed to cool or heat
  • You can access the living area while the motorhome is in motion.

Class C’s are a great choice for camping trips and any vacations that plan to be extended for a period of time. If you have a motorhome that comes with a large motor and chassis, you can also tow another vehicle as well.

Your typical Class C motorhome will come with a refrigerator, storage tanks for waste, dining room area, bathroom (with a shower, sink, and toilet,) storage compartments, and other several sleeping areas.


Even though the Class C motorhome is safe, in terms of driving and handling of the vehicle, there are some things that you should know.

  • If this is your first time driving a motorhome, make sure you log plenty of practice to get used to operating it. All vehicles have an adjustment period when driving them.
  • Get your insurance plan that specializes in motorhomes so you can be provided with extra coverage. Make sure you have roadside assistance for your motorhome, as well as checking the towing distance.
  • Keep a log of your usage for electrical. Motorhomes are only designed to operate certain things at once. A surge protector is a good idea to have if you want to connect multiple devices.
  • Inspect your motorhome before taking it on a vacation.
  • Research weather conditions when planning your road trip.
