Beautifully handcrafted interiors, fully equipped kitchens, the latest technology, powerful engines and floor plans for every need. On the Aria Class A Diesel motorhome, we simply call them standard features. The Aria Class A Diesel Pusher from Thor Motor Coach has everything you need and more.


Automotive Features

Cummins® Engine

Powering every Aria is a Cummins® diesel engine with plenty of horsepower and torque. When mated to the 6-speed Allison transmission, you have the pull you need for loaded cargo bays and the 10,000-pound hitch. Because Cummins is renowned for creating durable engines, you can trust your Aria to get you to your dream destination.

Freightliner® XC-R Chassis with Atlas Foundation™

Your home needs a solid foundation, and that’s why the Aria is hand-built on a Freightliner® XC-R raised rail chassis, then up-fitted with the Atlas Foundation™ makes for the perfect concoction. Your Class A RV is built to last, so your traveling can be stress-free.

Air-Ride™ and Sachs® Shock Absorbers

Air-Ride™ suspension and Sachs® shock absorbers ensure that your ride will be smooth every time. With the I-Beam and 55-degree wheel cut, you are in for an incredible driving experience. You’ll feel in control behind your diesel pusher, even while driving in the winter.



Modern Dash Radio

Touchscreen Bluetooth®, Sirius XM® and GPS

So what’s it like behind the wheel? You settle in for the drive-by adjusting the new power-adjustable reclining and swivel captain’s chairs with lumbar support, and the tilt and telescoping wheel. The Aria has dual monitors, one dedicated to your three-camera system, the other is your 10.1-inch touchscreen dash radio with Bluetooth®, GPS navigation and SiriusXM® radio. So turn up the radio, it’s time to blast your favorite Music for the Road.

Whisper Air™ Cooling System

Aria Class A diesel motorhomes are built around the way you live and entertain. So you always have more than enough room for you, family and friends. It’s not like travel trailers - this is beyond glamping. In your Aria, you won’t feel like you’re in a diesel pusher. You’ll be able to sleep soundly and complete your Summer Reading List thanks the ceiling ducted Whisper Air™ central cooling system.

“Wow” at your Campground

The LED lighting illuminates the porcelain tile and high-gloss glazed cabinetry with solid wood raised panel cabinet doors and nickel finish, making for a luxurious Class A RV. In the 3901 and 3701 floor plans, entertain your guests by watching the TV above the electric fireplace with remote control.

Aria Kitchen and Bath

Appetizing Mobile Meals

In the Aria, the kitchen is designed for you to create your favorite foods on the road. There’s plenty of room on the solid surface countertops and pull-out countertop extension. The double bowl stainless steel sink with solid-surface covers makes for extra space when you need it. You can use the dual burner electric induction cooktop or bake a favorite dish in the convection microwave. Check out some of the Mobile Meal recipes on our YouTube channel that pair perfectly with your Class A diesel motorhome.

Class A Diesel RV Bathroom

Because everyone has different wants and needs, Aria Class A motorhomes are available in a single bath, bath and a half, and two full bath floor plans. With one sink or two, the tankless water heater means you can wash up with water as hot as you want it.

Aria Bedroom

King-Size Tilt-A-View® Bed

In the bedroom, you will find a king-size Tilt-A-View® bed on every Aria. With USB ports in the nightstand, you can finish that chapter on your e-book. The large closets have adjustable shelves and the dresser tops are large enough for both of you to have a place for your morning mug of something warm as you get ready for the day.

Fall Asleep to a Movie

After a long day of play, you need to take a minute with your loved one to relax. Choose the perfect angle of your Tilt-A-View bed to unwind with your favorite love story on your 32-inch TV with Sony® BluRay® player. Regardless of your floor plan, you’ll love waking up in your Aria.

Mobile WiFi

Winegard® ConnecT™ 2.0

Traveling across the continent and getting away is what fuels your wanderlust but sometimes you have to come back to reality and get in touch with your coworkers or loved ones. In your Aria, we made that phone call or email easier for you. The Winegard® ConnecT™ 2.0 will work as your WiFi router, 4G hotspot and TV antenna. 



How to Set-Up Your Class A Diesel RV WiFi

To make things even easier for you, we made a video on our YouTube channel, explaining exactly How to Connect your Winegard Connect. Because when you’re on the road you shouldn’t take too much time on the little things, you should be making memories with your loved ones.


Efficient Camp Set-up

Rapid Camp+® Multiplex

A large touchscreen is a hub for the Rapid Camp+® Multiplex control system, which controls most of your Aria functions, including light dimming, extending or retracting slides, turning on the AC or furnace, and so much more. It is your all-in-one control center and it’s easy to use. Use the main panel or download the app to your phone or tablet. 

Easy to Follow How-To Video

To make camping even more efficient for you, we have uploaded a video to our YouTube channel, explaining How to use Rapid Camp+. Because when you’re vacationing with your loved ones, you want to focus on making the most of your memories.


Exterior Features

Storage Galore

Packing everything you need to take and everything you want to take have very different meanings. In the Aria, the illuminated basement with pass-through storage and easy slide tray allows you to take from both lists.

Ultimate Outdoor Relaxation

When you’re set up away from the crowds and enjoying the peace of those tree-lined places nature has to offer, there’s nothing more relaxing than sitting outside under the power patio. Maybe you’ll watch TV and have a cold drink and a snack. Or maybe you’ll sit and talk about where the road will take you next.

100-Watt Solar Charging System

Thoughtfully designed with nature lovers like you in mind. The solar charging system helps maintain the coach batteries, so when you’re traveling you can be more sustainable and eco-friendly. It is the great outdoors after all.
