Western Star Trucks has introduced three new Stratosphere sleepers, including 40- and 54-inch sizes as well as an 82-inch Ultra High model, the industry's largest sleeper by interior volume.

The three new sleeper configurations are now offered in addition to the existing 68- and 82-inch Stratosphere sleepers and feature the same distinctive walk-through design, roof-mounted air horns and marker lights and flat floor. The new configurations are now available for order on Western Star 4900 EX, 4900 SA, and 4900 FA models.
Matt Stevenson, manager of product strategy for Western Star Trucks, said, "By adding the new 40-, 54-, and 82-inch Ultra High configurations, we are now able to offer both over-the-road and vocational customers the best and broadest selection of walk-through sleepers in the industry."
A key feature in the design of all Stratosphere sleepers is the significant amount of additional headroom provided in the area between the driver's and passenger's seat. This headroom allows the driver or passenger to stand up and walk through the cab to the sleeper compartment without crouching or bending over. Additionally, because the floor is flat between the cab and the sleeper, the driver or passenger does not have to navigate steps or ledges as is the case with other sleepers on the market today.
The new 40-inch Stratosphere sleeper – the shortest walk-through sleeper offered by a Class 8 OEM – is ideal for vocational applications such as specialized hauling, construction, oil field and logging. In these types of applications where the sleeper may only be needed to meet operating requirements or for storing equipment, customers will benefit from the same stand-up room as a larger sleeper but without the added weight or reduced visibility.
The sleeper has four optional windows, giving drivers more than 16 square feet of added glass. In addition, the new configuration weighs less than 500 pounds.
Designed for heavy haul, regional haul, construction, and export applications, the new 54-inch Stratosphere sleeper is ideal for weight-conscious customers. Additionally, this sleeper features a 35-inch bunk and a full roof fairing and side extenders for over-the-road applications to help improve fuel economy.
Ideal for long-haul customers, the new 82-inch Ultra High Stratosphere sleeper offers the largest sleeper by volume on the market today. With more room to work and relax, this model is 13.8 inches higher than the original 82-inch Stratosphere and offers more than 30 cubic feet of additional living and storage space. The added space also allows for a fixed upper bunk that can be used in conjunction with a dinette seating option.
The 82-inch Ultra High model stands from ground to top of sleeper at more than 13 feet, improving airflow efficiency on a standard 13-foot, 6-inch van trailer.
