These modifications often require significant changes to the sleeper’s structure and layout. The finished trucks demonstrate how owners have worked with custom builders to incorporate unusual equipment while keeping their vehicles suitable for extended periods on the road.

A Volvo with Its Own Motorcycle Garage

A 2023 Volvo VNL built for Larry and Sarah Hendrix featured something rarely found inside a semi-truck sleeper: an enclosed garage for their Harley-Davidson motorcycle.

The couple commissioned ARI Legacy Sleepers to build a 240-inch sleeper on a Volvo with a 378-inch wheelbase. Rather than transporting the motorcycle on an exterior rack, the custom design provided a dedicated compartment behind the living quarters.

Accommodating the motorcycle was only part of the project. The sleeper also included a residential-style refrigerator, induction cooktop, convection oven and 52-inch shower, along with hardwood cabinetry and a dining area. A 100-gallon freshwater tank and 10,000-watt diesel generator supported the extensive onboard equipment.

The size of the build allowed the couple to retain substantial living space despite dedicating part of the sleeper to motorcycle storage. It also required a carefully planned interior arrangement to accommodate the garage alongside the kitchen, bathroom and other facilities.

By August 2026, the Volvo had accumulated approximately 441,000 miles, demonstrating that the completed custom build had seen extensive road use.

A Kenworth with Heated Floors for Alaska’s North Slope

Professional driver Chuck Woodcock commissioned a custom Kenworth sleeper with radiant floor heating for his routes between the lower 48 states and Alaska’s North Slope.

Working with Custom Studio Sleepers, Woodcock incorporated a heating system beneath the sleeper’s flooring, along with spray-foam insulation to help retain warmth during extremely cold conditions.

The sleeper also included a bathroom, shower, refrigerator and microwave. While those features are found in other custom trucks, the radiant heating system was a more unusual addition because it was integrated directly into the floor during construction.

The combination of insulation and built-in heating reflected the conditions Woodcock encountered during his regular trips into northern Alaska. Instead of relying entirely on conventional sleeper heating equipment, the design incorporated another method of warming the living area.

A Western Star with a Convertible Bedroom and Dining Area

A 2016 Western Star 5700XE operated by James and Shelly Russell featured a 120-inch sleeper with furniture that allowed the same space to function as both a bedroom and dining area.

The truck’s full-size bed could be folded away to reveal a table and two bench seats. With the bed lowered, the couple had a dedicated sleeping area, while raising it provided seating and dining space without requiring a separate room.

The Western Star also included a shower, toilet, sink, two-burner stove, refrigerator-freezer and microwave. These features were arranged around the convertible furniture to make use of the available space within the sleeper.

The Russells operated the truck while leased to Bennett Heavy & Specialized, transporting high-security government freight. Their custom interior allowed them to maintain separate sleeping and dining arrangements while traveling for commercial assignments.

A Peterbilt with a Complete Bathroom and Kitchen in a 108-Inch Sleeper

Ron and Dawn Marie Pickles commissioned a custom sleeper for their Peterbilt 384 that incorporated a bathroom, kitchen and dining area within 108 inches of space.

Working with American Reliance Industries, the couple developed an interior layout that included a shower, toilet, running water, large refrigerator and dining table. The design also had to accommodate Canadian dimensional restrictions affecting the truck’s overall configuration.

The enlarged sleeper added approximately 1,000 pounds to the vehicle, making weight management an important part of the project. Wide-base single tires and an aluminum fifth wheel were among the equipment choices used to help offset the additional weight.

The sleeper also incorporated a 40-gallon water supply, spray-foam insulation and an independent suspension system. Together, these features created an extensively equipped living area without requiring the much longer sleeper dimensions found on some other custom trucks.

The Pickles used the Peterbilt in lightweight, time-sensitive freight operations, where having a bathroom and kitchen onboard helped reduce the need for additional stops. The truck had already spent approximately two years in commercial service when its custom interior was publicly documented in 2013.

Custom Construction Beyond Conventional Sleeper Designs

Each of these trucks required a different approach to incorporating equipment that manufacturers do not typically include in standard sleeper configurations.

The Volvo’s extended sleeper provided room for a dedicated motorcycle compartment, while the Kenworth’s heating system was incorporated into the floor itself. The Western Star used convertible furniture to create two functional spaces within one area, and the Peterbilt accommodated extensive residential facilities while remaining within dimensional restrictions.

These builds illustrate the range of modifications possible when owners commission sleepers around specific requirements. Their unusual features were incorporated into vehicles that accumulated substantial road mileage or were used in commercial freight operations, showing that extensive customization was not limited to display trucks.

This year’s event will take place June 25 through June 27 at Bristol Motor Speedway, a venue widely known as “The Last Great Colosseum.” The location is no stranger to large-scale events, hosting everything from major racing series to football matchups and concerts. It also features one of the largest outdoor center-hung four-sided video screens in the world, along with an on-site campground for attendees.

Those planning to enter will want to move quickly. Early registration gives participants access to a reserved parking space and the ability to choose a preferred judging time, according to event organizers.

Sign-ups will stay open until 4 p.m. Central on June 26, or until the field reaches its 125-truck limit, whichever comes first.

The competition continues to draw attention across the trucking world, known for highlighting both appearance and the work behind the wheel. According to a news release, SuperRigs remains one of the industry’s premier events, bringing together the best-looking and hardest-working trucks on the road.

Participants this year will be competing for more than just recognition. The event will award over $25,000 in cash and prizes across more than 20 categories, including the top honor of Best of Show.

In addition, 12 drivers will earn a spot in the 2027 Shell Rotella SuperRigs Calendar, a feature that has become a goal for many entrants over the years.

The event is open to the public and designed to be family-friendly, offering a chance for attendees to get up close with custom rigs and meet the people behind them.

Winners in each category will be selected by a panel of judges, while the Shell Rotella team will determine which trucks make it into the annual calendar.

With limited entry spots and added incentives for early sign-up, this year’s show is expected to fill quickly as anticipation builds for Bristol.
