An ARV-designed Sprinter spec van, built in-house
Signature is a new Mercedes-Benz Sprinter, All-Wheel Drive, custom Advanced RV motorhome in production by our team. It’s an ARV-designed demonstration build – a coach we’re building as “the client,” using our most trusted ideas and a few new refinements we’ve been excited to explore.

The Idea
Nearly 200 Advanced RVs are already on the road, each shaped by the client who dreamed it. Signature is different. This time, our team is the client.
We planned for effiency – something that could move quickly through production. But as Signature passed from department to department, a pattern unfolded. As each craftsperson got their hands on it… they couldn’t help themselves.
They took their time. They refined. They pushed details further than necessary. Signature is what happens when artists and engineers are given permission to play.
A Layout Built for Daily Life
Signature is a 170” wheelbase, standard-length Class B motorhome with a full wet bath, a wide power sofa bed, and expanded rear storage. We moved the bed forward in the plan to create a larger gear bay behind it – the kind of space that makes long travel feel less limited.
The floorplan flows from front to back:
- Front cab with overhead shelf storage + bulkhead curtain for privacy and insulation
- Tall cabinet wall for clothes storage, refrigerator/freezer, and microwave
- Galley with sink and deep drawer storage
- Full wet bath (shower + sink + toilet) with split door + extended shower curtain for more elbow room
- Power sofa bed across the full width of the coach
- Expanded rear storage behind the bed
The Sofa Bed
Signature uses a new in-house sofa bed design. It builds upon a comfortable and rugged existing design that has been refined over a decade.
The ARV sofa bed uses three sections of large, expensive latex mattress on top of a supporting foam. When the deploy button is pressed, the three sections are guided by small electric motors into either the sofa or bed configuration. The sofa bed design enables gear storage below and behind the bed, and Signature’s new bed design improves the storage further.
Signature’s sofa bed is faster to deploy, uses lighter components, and places the under-bed mechanics in a better location – making the cargo space underneath the bed significantly more usable. It also draws less power in operation.
The bed dimensions are 66″ wide, 72″ long, and up to 91″ when the fold-down headboard is deployed.
Systems That Reduce Friction
Signature, and all Advanced RVs, are the culmination of a number of high-end technological systems that, when integrated, reduce the common frictions of road travels. The sights and experiences of the your journey are amplified when anxieties about power, plumbing, and maintenance fade into the background.
48V Lithium Power
Signature uses our in-house, UL-listed 48V battery system:
- 16.4 kWh capacity
- 4,000W inverter/charger
- 48V high-output secondary alternator
- Temperature control, charge controller, and high-end battery management
- Single touchscreen interface for monitoring and control
- Surge protection
Signature stores considerable energy and it recharges itself quickly. The high output air conditioner can run for over a dozen hours straight. The battery will recharge with only an hour or two of engine runtime.
All this means fewer compromises when you’re off-grid. You can expect to take month-long adventures without ever plugging in.
Four-Season Water + Reliable Monitoring
- 40 gallons fresh
- 28 gallons gray
- 18.5 gallons black
Signature also features a leap forward in tank monitoring technology. For years, we’ve sought to replace air-pressure sensors, which are susceptible to sediment buildup, with something more reliable and accurate.
Signature uses external radar tank sensors to monitor tank levels. These sensors provide accurate readings without living inside the tank environment. We’ve performed this upgrade for a couple clients as well, and they all note the improvement.
In addition to the tanks, other plumbing designs improve day-to-day functions. integrated filtration and UV treatment make drinking water from the fresh tank simple and low-hassle; our new nerf bar body kit makes filling and emptying tanks easier; and the spacious bathroom continues to surprise visitors used to what’s typically crammed in the Class B footprint.
Comfort in Real Weather
Signature builds on our proven four-season foundation – so travel stays comfortable in any weather.
A diesel-fired heating system provides warm cabin and on-demand hot water, paired with careful insulation and sound control work throughout the chassis shell. The plumbing lines are insulated and placed inside the vehicle. The tanks are temperature-controlled and monitored by the onboard computer system.
Chassis and Driving
Signature is built on a 2023 Mercedes-Benz Sprinter AWD with the new 4-cylinder bi-turbo diesel engine and 9-speed transmission – a drivetrain many long-time Sprinter owners recognize as a meaningful step forward in responsiveness and efficiency.
It’s also equipped with Mercedes driver-assistance packages (including features like adaptive cruise control), and includes an extended Mercedes warranty through May 2029.
We also replace the factory rear suspension with a high-end, computer-controlled air suspension system to reduce sway, smooth harsh roads, and support long-term durability by reducing vibration through the living space.
A Bold Look
Because Signature is a demonstration build, we knew we wanted to try something unique. You’ll see multiple blue tones inside, and a vibrant durable, textured lower exterior coat outside.
If you’ve been with us a while, you may remember Baja – another bold ARV color direction that surprised people and became a favorite. (Link to Baja video.)
The Fun of It All
Signature also captures the personality of the team that built it:
- Our electrical team experimented with new colorful and programmable exterior lighting.
- An enhanced amplifier and speaker system to more clearly and powerfully play the soundtracks to your journeys
- Alex, our upholsterer, brought his Italian sports car experience to Signature. He decided to have fun and do something beautiful.
Signature started as a “demonstration build.” It’s becoming a small gallery of what our shop loves to do.
Availability
Signature is available to claim and purchase now. The coach is largely defined at this stage, but we’re always happy to talk through possibilities and fit.
If Signature matches your travel style – and you want to be part of its final stretch – we’d love to connect.
Submit a contact form or give us a call, and we’ll talk through timeline, pricing expectations, and next steps. If you’re able, we also encourage a visit to Cleveland. The best way to understand a coach like this is to step inside it.
