The Smallest RV is Small AF

If you’re looking for a small drivable RV, you’ll be looking at Class B camper vans. This type of RV is the smallest option in the motorhome line up. But did you know that you can get a camper van that’s less than 20 feet long? It’s true! An Italian company has designed the Wingamm Oasi 540 at under 18 feet. 

So if you want to hit the road in style but in the smallest van possible, this is a great option. Read on to learn more!

What Is a Class B RV? 

Part of the motorized line of RVs, a Class B is the smallest motorhome type available. Most Class Bs offer no slide-outs but still have the basic necessities for a weekend camping trip. Some will feature a wet bath, while others will only have an outdoor shower. Most will come equipped with a kitchen sink, cooktop, and refrigerator. They’re generally 21 feet to 24 feet long.

A Class B RV is self-contained, which means there’s freshwater storage, a waste holding tank, a furnace, an air conditioning unit, and a 12-volt battery. It’s on an automotive van chassis like a Mercedes Sprinter Van, Ford Transit, or RAM ProMaster.

What Is the Difference Between a Class B and Class C RV?

The biggest difference between a Class B and Class C RV is the size. Class Cs can be as small as 25 feet but can also stretch to 35 feet in length. Also, a Class C features the cabover bed for additional sleeping space. 

Class Bs are easier to drive and maneuver around city streets. And because they’re more like the size of a cargo van, they’re more fuel efficient than Class Cs.

What Is the Smallest Class B RV?

Made in Italy, the smallest Class B RV is the Wingamm Oasi 540. Wingamm has been manufacturing RVs since 1977, specializing in high-tech, fully stocked camper vans. This Oasi 540 is 17 feet 9 inches long and offers an interior height of 6 feet 6 inches, except under the pull-down bed, where the ceiling height is limited to just 6 feet 1 inch.

About the Oasi 540.1

This sleek Class B is only a prototype. At present, it’s on a Fiat Ducato chassis, but it will be on a RAM ProMaster chassis when brought to the United States. The starting price is $145,000.


The Oasi 540.1 is considered a micro Class B because it’s only 17 feet 9 inches long. However, it can still sleep and seat up to four people. It’s custom molded with a fiberglass shell, which gives it a smooth look and provides excellent insulation. 

The Truma Omni system provides hot water and acts as the camper’s furnace. The ducted furnace vents run throughout the camper and provide radiated heat through the flooring. The air conditioning unit also functions as a heat pump to provide two heat sources.

The Oasi 540.1 comes standard with one battery you can upgrade to a lithium battery. There are 210 watts of solar on the roof, and owners can add an inverter if desired. The freshwater tank is about 26 gallons, the gray tank is about 18 gallons, and the cassette toilet holds 5 gallons.


To the right of the entry door, you’ll find two swivel seats in the cab, a couch, and a removable table. A long counter runs opposite the lounge space and includes a kitchen sink, stovetop, refrigerator, and storage cabinets below and above the space. The couch transforms into additional seats for traveling and a sleeping area for two people. The second bed is up at the ceiling, and you can easily pull it down to provide another sleeping space.

In the rear of the unit is the wet bath. You’ll find a shower, cassette toilet, and sink. A medicine cabinet above the sink and a storage cabinet below the sink provide storage. Finally, a floor-to-ceiling closet is also in the rear of this micro Class B.


There is a rear storage unit where owners could put extra cassettes for the toilet or other items. You can access the front storage unit from the outside and inside, meaning owners can easily grab an item without going outside and around the camper. Another cool feature is the trash can attached to the door. When the door is swung open, the trash can is now accessible to the outside.

There are so many places for storage inside this micro Class B. Even with the smaller length, you won’t be searching for places to put items. The manufacturers have taken great care to maximize the space. Having sleeping space for up to four people with the pull-down bed near the van’s roof and the convertible couch is a huge plus. In addition, the wet bath is very spacious, large enough to turn around and move about without hitting your elbows on the walls.

What Is So Great About a Small Class B RV? 

A small Class B RV like the Wingamm Oasi 540 makes traveling easier. It’s easier to drive for someone who has never driven anything larger than a Honda Civic and easier to maneuver in tight spaces like city streets or small campsites. 

A Class B RV can double as an errand car when you need to get groceries or find a dump station. Can you imagine driving a 40-foot Class A motorhome to Kroger’s just to pick up a loaf of bread?

They’re also more fuel efficient because of their small size. RVs are notorious for their poor fuel mileage. Class As barely get above 10 mpg. But a micro Class B will sometimes get over 20 mpg. This saves money at the pump as well as time when you travel.

If you want to camp in remote locations and have endless options for places to go, a micro Class B may just be the perfect fit.
