What is a Class B Plus RV & How Is It Different From A Class B or C?

Class B Plus RV? Hmmm… In general, when the various classes of motorhomes are discussed, Class A, B, and C RVs are covered, as well as travel trailers, fifth wheels, and toy haulers. But motorhomes are limited to Class A, B, and C rigs. Or are they?

We know that Class A RVs are the largest and most luxurious of the three classes of motorhomes (with diesel pushers sitting at the top of that class), Class B is the smallest (often referred to as a campervan), and Class C is the middle child, usually distinguished by a bed or entertainment center/storage covering the entire area over the cab.

But you’ve probably been hearing of a newer “class” of RV, notably the Class B Plus (or Class B+). But what exactly is a Class B Plus RV, how will you know one when you see one, and why might you want one?

In this post, we’re covering the ins and outs of the Class B Plus motorhome – what it is, how it differs from Class A, B, and C RVs, and what would it cost to buy one?

What is a Class B Plus RV?

From the perspective of federal regulations, a Class B Plus motorhome is technically a Class C RV. Let’s say that again for the sake of clarity:

A Class B Plus is technically not in a class of its own but is instead a type of Class C RV. All federal regulations that apply to Class C RVs apply to the Class B Plus category of RVs, too.

Now that we’ve dropped that little bombshell absorbed that interesting information, let’s take a look at what makes an RV a “Class B Plus”! As you might imagine, the term “Class B Plus” refers to a motorhome that sits somewhere between a Class B and a Class C RV. Like the Class C, the B Plus is wider than a Class B and is built on a truck chassis.

Unlike Class C RVs, the Class B Plus doesn’t have a bunk (or storage/entertainment area) stretching all the way over the top of the cab. And that obvious structural difference is pretty much how you can tell the difference between a Class B Plus motorhome and a Class C motorhome when you see one driving down the road.

What’s the Difference Between a Class B and Class B Plus?

As we’ve established, a Class B Plus is built on a truck chassis. A Class B RV, on the other hand, is built from a van. Often referred to as a camper van, Class B RVs are essentially long, high-top vans made into motorhomes with all (or most of) the features of a larger RV but in a smaller package.

The traditional Class B RV contains all of the features of a motorhome within the confines of the factory-built van body, without any additional walls, floors, or roofs added in. As a result, Class B RVs pack their bathrooms into tight spaces, which is why most have a wet bath — that is, a shower, toilet, and tiny sink occupying one small space (and yes, they all get wet when the shower’s used, hence the term “wet bath!”).

Class B RVs typically have smaller refrigerators, two-burner propane stoves, and storage everywhere there’s a space for things to be stored. They usually don’t have the space for a dedicated dinette, but they do often have front captain’s seats that swivel around to face the rear of the RV and small tables (sometimes one in the front and a second in the back) that can be placed in use or stored.

Class B Plus rigs can be laid out somewhat similarly, but because they’re wider, longer, and taller, differences are afforded by the additional space. For example, a Class B Plus might have a little dinette, a larger refrigerator, a slide, and sleep 1-2 more people than a Class B RV could sleep (of course, all of this depends on where you obtain your information… more on that in a moment).

One of the most appreciated features of a Class B Plus compared with a Class B is that a B Plus is often large enough to accommodate a dry bath, that is, a separate toilet and shower area (so you’re not showering all over the little sink and toilet as you would in a wet bath). Class B Plus rigs also tend to offer more storage on both the interior and exterior of the motorhome and somewhat larger fresh, gray, and black holding tanks as well. In addition, the larger chassis affords the Class B Plus motorhome more towing capacity and a greater GVWR (Gross Vehicle Weight Rating), so it can carry more gear.

When reviewing the differences between a Class B and B Plus, it’s easy to see why the Class B Plus is technically classified as a member of the Class C family. The B Plus is quite clearly more like a Class C than a Class B.

How Big Are Class B+ RVs?

A typical Class B Plus motorhome is between 23’ and 25’ in length, but they can be longer. They’re generally easy to park and maneuver through city streets or over terrain that may be a bit more remote. There are versions of the Class B Plus that are able to accommodate a slide or two, offering even more room to the interior living space. The larger the Class B Plus rig is, the larger the holding tanks tend to be, and the more storage and sleeping capacity the rig affords.

Most Class B Plus motorhomes come with exterior storage large enough to accommodate such things as bicycles, kayaks (especially inflatable ones), and golf clubs. And, they’re typically designed to comfortably travel and sleep 2-4 people, whereas Class C RVs are large enough to accommodate more.

With all of that said, if you do a little research online, you’ll find lots of conflicting information on Class B Plus rigs. Some articles say they’re built for no more than two people. Others say the larger units have slides and plenty of room to sleep four or more. The truth is this: The Class B Plus evolved from requests from folks in the market for a Class C-sized rig who didn’t want the over-cab piece.

So a Class C-sized RV with a cutaway truck chassis was designed, and the term “Class B Plus” was born, strictly as a marketing tool. That’s right — it’s a made-up marketing term to indicate the design difference and to appeal to a particular audience (reminder: these so-called “Class B Plus” rigs are technically Class C RVs).

Which is why it’s no wonder that the details of Class B Plus motorhomes vary depending on who’s reporting. A “Class B Plus” isn’t so much a specific entity as it is a marketing tool.

Features & Amenities of a Class B Plus Motorhome

B Plus rigs are often marketed as small luxury RVs with many of the amenities of a Class A rig, only smaller. Class B Plus RVs are indeed often high-end, small motorhomes for sure (and their prices tend to reflect this – more on that in the next section).

A Class B Plus motorhome typically has a permanent bed (most often a queen, though some manufacturers have begun to offer Murphy beds, which make for additional interior space during the day). Some are all-wheel-drive, and many have features such as lighted awnings, roof-mounted solar panels and inverters, larger refrigerators than their Class B counterparts, entertainment centers with storage over the back of the cab area, dinette lounges, high-end galley (kitchen) amenities, and pretty spacious (dry) showers.

Many of the Class B Plus motorhomes offer European design, with sleek exterior lines and relatively fine interior finishes.

How Much Does a Class B+ Cost?

Many people look toward the Class B Plus as a nice midway between the smaller, van-like Class B and the larger, more boxy Class C RVs with what they suspect will be lower cost compared with the Class Cs. Not so! Class B Plus motorhomes are often priced relatively high, running anywhere from $70,000 to $200,000 (most running over $100,000), depending on the manufacturer and amenities.

A Class B Plus RV may afford you a sweet ride and a relatively luxurious small motorhome, but it won’t offer you a budget RV by any means, and it won’t save you money over a Class C. Class C RVs are almost always less expensive than Class B Plus RVs.

How Many People Can a Class B+ Sleep?

We touched on this earlier in the article, but most Class B Plus RVs are designed to accommodate two adults and maybe a small child or two comfortably (in the converted dinette), though some manufacturers offer floor plans that can sleep three or four adults.

NOTE: seatbelts provided in the dinette area allow for more than two people to travel safely as well, but be sure to check the specs for any unit you’re considering buying or renting before assuming.

Are Class B Plus Motorhomes Good for Full-Time Living?

This is a tough question for two guys who lived full-time in a 43-foot diesel pusher. Obviously, we prefer a fair amount of room for full-time living, working, and traveling (although we’d have happily downsized if there had been a 35′ Class A diesel pusher floorplan we actually wanted). With that said, while traveling outside of North America, we’ve traveled and lived in Class B Plus RVs for several weeks at a time, and we were perfectly comfortable.

Would we want to live and work full-time, day after day, in a rig that size? Probably not. But lots of people live in vans and Class B RVs full time – and even in minivans, cars, and SUVs — and we’re pretty sure they’d consider living full time in a Class B Plus RV quite a luxury.

Conclusion

Despite the fact that it’s sort of a “fake” class created as a marketing tool that actually belongs to the Class C family, a Class B Plus RV is a great traveling rig with just the right amenities for the right travelers. Larger, and therefore roomier, than a Class B RV, and less boxy and top-heavy than a Class C RV, the Class B Plus motorhome offers plenty of comfort and ease of driving that delivers just the right balance for many RV owners and renters.
