The Three Main Motorhome Classes
Motorhomes (RVs with their own engine) come in three classes.
Class A is the largest and most luxurious.
Class B is the most compact.
Class C sits in between and is the most popular rental for families.
Beyond motorhomes, there are towables: travel trailers, fifth wheels, and popup campers.
Those require a separate tow vehicle and a different skill set.
We cover them briefly below.
Class A: The Big Rigs
Class A motorhomes are built on a dedicated bus or commercial truck chassis.
They range from 25 to 45 feet and offer full residential amenities: slide outs, king beds, full kitchens, washer/dryer hookups, and multiple TVs.
New, they run $100,000 to $300,000+.
On Outdoorsy, rentals typically cost $200 to $400 per night.
Best for: Full timers, luxury travelers, large families who want a home away from home experience with no compromises on space.
Trade off: Fuel economy of 6 to 10 MPG and a steep learning curve for backing into tight campsites.
Class B: Camper Vans
Class B rigs are full-size vans converted into self-contained campers, such as the Mercedes Sprinter or Ford Transit.
They measure 17 to 23 feet and sleep two adults comfortably.
New prices run $60,000 to $150,000.
Rentals average $150 to $250 per night.
Best for: Couples, solo travelers, van life curious, and anyone who wants to park in a city or navigate mountain switchbacks.
Trade off: Limited bathroom space, minimal storage, and can feel cramped on longer trips.
Class C: The Middle Ground
Class C motorhomes are built on a cutaway truck or van chassis with a distinctive cab-over bunk above the driver's cab.
They span 20 to 35 feet and sleep 4 to 8 people.
New prices range from $80,000 to $200,000.
Rental rates run $150 to $300 per night.
Best for: Families, first-time renters, and anyone who wants Class A amenities without the Class A footprint.
Trade off: The cab-over bed is great for kids but inconvenient for adults.
Fuel economy is 8 to 12 MPG.

What About Towables?
Travel trailers, fifth wheels, and popup campers are towed behind a separate vehicle.
They can be cheaper per night but require a truck or SUV rated for the tow weight, along with towing experience.
If you already own a capable truck and are comfortable towing, a travel trailer rental can save $50 to $100 per night over a comparable motorhome.
If you don't, stick with a motorhome for your first trip.

Which Class Should You Rent First?
Family with kids
Class C. The cab-over bunk turns into a kid adventure, the bathroom is full-size, and you can park at most campgrounds without worrying about length.
Couple or solo traveler
Class B. Park anywhere, drive like a van, and save on fuel. If you need more space, step up to a small Class C.
Extended trip or full-timing test
Class A. The extra investment per night buys you a real kitchen, real bedroom, and enough storage to live out of for weeks.
Budget conscious first timer
Entry level Class C. Best balance of space, drivability, and nightly cost. Read our first time tips before you go.

FAQ
Do I need a special driver's license to rent a Class A RV?
In most US states, a standard Class C driver's license is all you need, even for a 45-foot Class A motorhome. A handful of states require a non-commercial Class B or Class A CDL for vehicles over a certain weight, so check your state DMV before you book.
Which RV class is easiest to drive for a first timer?
Class B camper vans are the easiest: they drive like a large cargo van. Class C is a close second. Class A motorhomes require the most adjustment, especially backing up and judging width on narrow roads.
Can I park a Class A or Class C at a regular campsite?
Most full-hookup campgrounds accommodate all three classes. If you're planning national park stays, check site length limits, as some historic campgrounds cap out at 27 or 35 feet, which rules out larger Class A rigs.
Is renting a Class B worth it if I want to sleep four people?
Generally no. Class B vans comfortably sleep two adults. For four people, especially families with kids, a Class C is the smarter choice. It costs about the same per night but gives you a proper dinette, larger bathroom, and the cab-over bed.
