A Class B+ recreational vehicle (RV), also sold as a “Super B,” is a motorhome built on a van chassis with a raised or widened roof, sitting between a Class B camper van and a Class C motorhome in size and amenities. Despite the marketing label, the RV industry generally classifies it as a Class C motorhome.
What Is a Class B+ RV?
A Class B+ motorhome starts with a van chassis, typically a Mercedes-Benz Sprinter, Ford Transit, or Ram ProMaster, and adds a raised or popped roof and sometimes a wider body. The result is interior headroom and living space that a standard Class B camper van cannot match, without reaching the full footprint of a Class C. Most floor plans include a dedicated bathroom and sleeping space for two to four people.
“Class B+” is a marketing term from manufacturers and dealers, not an official category. The Recreational Vehicle Industry Association (RVIA) generally classifies these units as Class C motorhomes. If you are also weighing standard camper vans, Class B motorhome manufacturers and models covers them in detail.
The “Super B” and Industry Classification Note
“Super B” is used interchangeably with “Class B+” by some manufacturers and dealers, including Camping World, to signal that the unit exceeds a standard Class B in size and features. Being classed as a Class C can matter practically: it can affect financing terms, insurance categories, and campground site assignments, so it helps to confirm how your lender and insurer categorize the unit before you buy.
Class B vs. Class B+ vs. Class C: Side-by-Side Comparison
The table below compares the three classes on the dimensions buyers use most. The Class B+ length range is based on current models such as Thor Motor Coach’s Gemini and Winnebago’s EKKO, and the Class C range on Thor Industries’ Class C reference.
Fuel economy figures are base-chassis miles per gallon (MPG) ratings from the U.S. Environmental Protection Agency (EPA) at fueleconomy.gov. Once an RV conversion adds weight, real-world MPG runs lower than these ratings.
| Attribute | Class B | Class B+ | Class C |
| Typical length | Under 22 ft | 23 to 26 ft | 23 to 39 ft |
| Roof height | Factory van roof | Raised/popped roof | Raised cab-over section |
| Sleeping capacity | 2 to 3 | 2 to 4 | 4 to 8 |
| Bathroom | None or wet bath | Dedicated (most plans) | Full bath standard |
| Dominant chassis | Sprinter, Transit, ProMaster | Sprinter, Transit, ProMaster | Ford E-Series, Ram 3500 |
| Base chassis MPG (EPA) | 18 to 24 (diesel/gas) | 15 to 22 (diesel/gas) | 10 to 14 (gas) |
Figures vary by floor plan, options, and model year. Confirm current pricing with a dealer.
Which Class Fits Which Campsite?
Class B+ units at 23 to 26 feet fit the majority of standard national park and state park sites without issue. Class C units at the upper end, 35 feet or longer, may be restricted to pull-through or premium sites. If you regularly target smaller or backcountry campgrounds, a B+ gives you more site flexibility than a longer Class C.
Named 2026 Class B+ Models and Specs
These 2026 models show how the B+ category plays out on a dealer lot. Starting prices are manufacturer’s suggested retail price (MSRP) figures, and dealer pricing and availability vary, so it helps to confirm current numbers with the manufacturer.
| Model | Chassis | Length | Sleeping | Bathroom | Starting MSRP |
| Thor Gemini | Ford Transit | 23 ft 7 in to 25 ft 10 in | 2 to 3 | Full bath (toilet and shower) | Contact Thor Motor Coach for current 2026 pricing |
| Jayco Granite Ridge | Ram ProMaster | Approx. 21 to 24 ft | 2 to 4 | Wet bath | Contact Jayco at jayco.com for current 2026 pricing |
| Airstream Atlas | Mercedes-Benz Sprinter | Approx. 24 ft | 2 | Not listed | Contact dealer for current pricing |
Off-Road and 4×4 Class B+ Options
Some B+ models are available with 4×4 drivetrains for buyers who want overland capability. The Entegra Launch 4×4 and Pleasure-Way Rekon 4×4 are two examples cited in the B+ market. These models share the same raised-roof van chassis platform but add all-wheel or four-wheel drive. If backcountry access matters to you, it helps to confirm the specific drivetrain with the dealer before purchasing.
Class B+ vs. Class C Motorhome: Which One Is Better for You?
The core trade-off is maneuverability and fuel economy versus living space. A B+ suits couples or small families who want more comfort than a camper van but need campsite flexibility and reasonable fuel costs on longer trips. A Class C suits larger families or full-time travelers who need slide-outs, more sleeping berths, or a larger kitchen.
One financing note: because B+ units are generally classed as Class C motorhomes, lenders and insurers may categorize them the same way. It helps to confirm with yours before you buy. For a deeper comparison, see Class B vs. Class C motorhome.
- Choose a B+ if: you are a couple or a small family, you prioritize campsite flexibility and fuel economy, and a dedicated bathroom matters more to you than slide-outs.
- Choose a Class C if: you travel with more than two adults, you want slide-outs for added interior width, or you need larger fresh and grey water tanks for extended full-time travel.
Fuel Economy: B+ vs. Class C
A B+ on a Sprinter diesel chassis typically outperforms a gas-powered Class C on fuel economy, based on EPA base-chassis ratings. The gap narrows for diesel Class C units on the Ram 3500 platform. It helps to check the EPA listing for the specific base chassis (for example, the 2026 Sprinter 2500 diesel) and expect real-world figures to run lower once RV conversion weight is added.
Pros and Cons of a Class B+ RV
Every RV class involves trade-offs, and the B+ is no exception. This summary covers the ones specific to the B+ category so you can weigh them before you decide.
Pros:
- More headroom: Gives you more headroom and room to move than a standard Class B camper van.
- Dedicated bathroom: Most floor plans include one, which makes extended trips practical.
- Campsite fit: Meets standard campsite size limits better than a 30-plus-foot Class C.
- Fuel economy: Uses less fuel than a full Class C on a comparable gas chassis.
- Parking flexibility: Parks in more locations than a longer Class C.
- Financing: Class C classification may simplify financing and insurance.
Cons:
- Higher cost: Costs more than a comparable Class B camper van.
- Driveway limits: Remains too large for many residential driveways and homeowners association (HOA) driveway rules.
- Narrower interior: Is narrower inside than a Class C with slide-outs.
- Garage clearance: Has a raised roof profile that typically exceeds standard residential garage clearances.
- Floor plans: Offers limited floor plan variety compared to Class C.
Is a Class B+ RV Good for Full-Time Living?
A Class B+ works well for couples or solo full-timers who want the maneuverability of a van-based platform without sacrificing a dedicated bathroom. Fresh and grey water tank capacity is smaller than in a full Class C. Full-time owners typically plan for more frequent hookup or dump-station stops than they would with a larger motorhome.
Where to Store a Class B+ RV
Most Class B+ motorhomes stand 9 to 11 feet tall with the raised roof profile and run 23 to 26 feet long. Standard residential garages typically clear 7 to 8 feet of interior height and 20 feet of depth. The vast majority of B+ owners cannot store at home on height alone, before accounting for length.
HOA rules in many communities also prohibit extended parking of motorhomes in driveways regardless of size. That leaves three main options:
- Outdoor uncovered storage: The most affordable choice, and it suits mild-climate markets where UV exposure and precipitation are lower concerns.
- Outdoor covered or canopy storage: Protects from UV, rain, and light debris, and is the most common choice for B+ owners.
- Indoor garage storage: Provides full protection and is available with climate control at some facilities, which suits owners with sensitive interiors or onboard electronics, including inverter systems.

Outdoor Covered vs. Indoor Garage Storage for a Class B+
A covered canopy space accommodates the height and length of most B+ units and costs less than a full indoor garage. Indoor garage spaces large enough for a 26-foot, 11-foot-tall unit are available but less common than standard car-storage units, so availability varies by facility. If your B+ has sensitive finishes, a built-in inverter, or factory solar panels, indoor storage reduces long-term exposure risk. It helps to check unit dimensions against your specific vehicle’s height and length before reserving.
Final Thoughts on Storing a Class B+ RV
A Class B+ motorhome’s raised roof and overall length put it outside what most home garages and HOA driveway rules can handle. RecNation RV storage offers outdoor covered and indoor garage spaces sized for motorhomes at 70 facilities across Arizona, California, Florida, Kansas, Missouri, South Carolina, Tennessee, and Texas. Spaces are available by the month, so you can store between trips without a long-term commitment.
Frequently Asked Questions
What is a Class B+ RV?
A Class B+ RV is a van-chassis motorhome with a raised or popped roof that gives more headroom and living space than a Class B camper van. Most sleep two to four people and include a dedicated bathroom. Manufacturers use “Class B+” as a marketing name, while the RV industry generally classifies these units as Class C motorhomes.
How is a Class B+ different from a regular Class B?
A standard Class B camper van stays under 22 feet long and uses the van’s factory roof height, often leaving interior headroom under 6 feet. A Class B+ extends that platform with a raised or popped roof, adding 6 to 12 inches of headroom and room for a dedicated bathroom and more sleeping capacity, typically in a 20 to 25 foot overall length.
Are Class B+ RVs good for full-time living?
Class B+ RVs suit couples or solo full-timers who value maneuverability and a dedicated bathroom over maximum space. The main limit is smaller fresh and grey water tanks than a full Class C. Full-timers usually plan for more frequent hookup and dump-station stops.
How fuel efficient are Class B+ motorhomes?
Class B+ motorhomes are generally more fuel efficient than gas-powered Class C units, especially on a Sprinter diesel chassis. RV conversion weight pulls real-world MPG below the base chassis EPA rating, so the published figure works as an upper limit rather than a travel average. The fueleconomy.gov listing for the specific chassis gives the baseline.
Can a Class B+ RV fit in a standard residential garage?
A Class B+ RV does not fit in most residential garages. Overall height of 9 to 11 feet exceeds a typical 7 to 8 foot garage door opening by a wide margin, and 23 to 26 feet of length exceeds most garage depths. Owners without home storage usually choose an outdoor covered space or an indoor unit at an RV storage facility.
What does “Super B” mean in relation to Class B+ motorhomes?
“Super B” is an informal dealer and manufacturer name for a Class B+ motorhome. Listings under either name describe the same van-chassis unit with a raised roof, and both are generally classed as Class C motorhomes. Camping World is one retailer that uses the term.
