Get FinancingClass B vs. Class B+ Motorhomes: What’s The Difference & Which Is Right For You?
You may have seen a term popping up on RV lots and websites around the country in recent years: the Class B+ motorhome. As the name implies, it’s similar to a Class B, but what makes a Class B+?
While not recognized as an official category by the Recreational Vehicle Industry Association—the governing body that identifies RV classifications—some sellers and manufacturers use the term to describe units they feel don’t quite meet the standard definition of either a Class B camper van or the larger Class C motorhome.
Let’s take a how these classes differ, and which one might be the best option for you.
What Is A Class B Motorhome?
A Class B motorhome, also known as a “camper van,” is the smallest category of motorized RV. These motorhomes are built on a full van chassis, such as the Mercedes-Benz Sprinter, Ram ProMaster, or Ford Transit, using the manufacturer’s original body.
Because they retain the van’s factory shape, Class B motorhomes are known for:
- Compact size
- Easy drivability
- Condensed amenities through convertible spaces
Class B RVs typically range from 17 to 24 feet (5.2 to 7.3 meters) in length and are designed to maximize efficiency in a small footprint.
What Is A Class B+ Motorhome?
A Class B+ motorhome fits the space between Class B camper vans and larger Class C motorhomes. While they are still built on a van or cutaway chassis, Class B+ motorhomes feature a custom-built coach body rather than the original van shell. Because it lacks an official definition, what is labeled a Class B+ can vary from manufacturer to manufacturer.
Key characteristics of Class B+ motorhomes include:
- A wider, taller body than Class B vans
- More interior space and storage
- Some models have a cabover bunk like a Class C
Class B+ RVs typically measure 23 to 26 ft (7 to 8 m) long, offering more room without jumping to a full-size motorhome.
Size, Weight & Capacity: How Do They Compare?
| Class B | Class B+ |
Size | Narrower, lower profile; fits in many standard parking spaces | Wider and taller; still compact but more noticeable on the road |
Weight | Lighter overall, usually well under 10,000 lbs (4,500 kg) GVWR | Heavier due to added structure and amenities, often approaching Class C weights |
Passenger & Sleeping Capacity | Typically sleeps two (sometimes three to four with pop-tops or convertible seating) | Often sleeps three to four comfortably with dedicated beds or larger sofas |
Interior Layout & Living Space
Class B Interiors
Class B interiors implement a multi-purpose design. Almost every component serves more than one function.
Common features include:
- Convertible beds (dinette-to-bed or rear sofa-to-bed)
- Compact kitchens with limited counter space
- Minimal storage
- Lower ceiling height
The result is an efficient but sometimes tight living area, best suited for minimalist travelers.
Class B+ Interiors
Class B+ interiors feel more like traditional RVs.
They often include:
- Dedicated sleeping areas
- Larger kitchens with more counter space
- Slide-outs (on some models)
- Higher ceilings and wider walkways
This added space makes Class B+ motorhomes more comfortable for longer trips.
Bathroom Types: Wet vs. Dry
Bathrooms are one of the biggest differences between these two motorhome classes. Class B motorhomes almost always have a wet bath, if they have any bath at all. A wet bath combines the shower, toilet, and sink into one waterproof space. When you shower, the entire bathroom gets wet. This saves on space and doesn’t add a lot of weight to the RV, but the room has to be allowed to dry out after each use.
A dry bath separates the shower from the toilet and sink, providing a more residential feel, but it takes up more space. Some Class B+ motorhomes offer dry baths or at least larger wet baths than those found in camper vans.
Amenities & Features
Class B Amenities
Despite their size, Class B motorhomes still pack a lot of features:
- Small kitchenette (sink, fridge, microwave)
- Induction cooktops or propane burners
- Solar panels and lithium batteries
- Swivel cab seats
- Limited wardrobe and exterior storage
They excel at off-grid and urban travel but require compromises in space.
Class B+ Amenities
Class B+ motorhomes offer more traditional RV comforts:
- Larger refrigerators
- Full galleys with more prep space
- Additional TVs and entertainment systems
- Larger holding tanks
- More exterior storage compartments
They are better suited for travelers who want comfort without a large motorhome footprint.
Why Choose A Class B RV?
If you plan to travel light, stay flexible, and prioritize ease of driving, a Class B camper van is a strong choice. For solo travelers, couples, weekend adventurers, and travelers who value fuel efficiency and maneuverability, a Class B motorhome is a great option.
Popular Class B examples include:
Why Choose A Class B+ RV?
If comfort, storage, and interior space matter more than compact size, a Class B+ motorhome delivers a balanced solution. They are ideal for couples who want extra space, small families, RVers upgrading from camper vans, and longer road trips or full-season travel.

Minimalist Yet Luxe
Both Class B and Class B+ motorhomes offer excellent ways to travel, but the right choice depends on how—and how long—you plan to RV. Class B motorhomes shine in agility and efficiency, while Class B+ models provide added comfort and livability without stepping into full-size RV territory.
