The three new Stratosphere sleepers from Western Star Trucks are for both over-the-road and vocational customers. They include 40- and 54-in. sizes as well as an 82-in. Ultra High model, said to be the industry’s largest
sleeper by interior volume. The new configurations are now available for order on Western Star 4900 EX, 4900 SA, and 4900 FA models. They join the existing 68- and 82-in. Stratosphere sleepers and feature the same walk-through design, roof-mounted air horns and marker lights, and flat

A key design feature in the Stratosphere line is the amount of additional headroom provided in the area between the driver’s and passenger’s seat – there’s no crouching or bending over when the driver or passenger stands up and walk through the cab to the sleeper. And unlike some others, the floor is flat.

The 40-in. sleeper, the shortest walk-through model offered in any class 8 truck, is ideal for specialized hauling, construction, oil field, logging, and other vocational uses. You get the same stand-up room as a larger sleeper
but without the reduced visibility, which is crucial in some applications. You can also order four optional windows — front Vista, left- and right-hand side, and rear – amounting to more than 16 sq ft of added glass. It weighs less than 500 lb and sports a 31-in. bunk.

The 54-in. Stratosphere sleeper is designed for heavy haul, regional haul, and construction applications, especially for weight-conscious customers. It has a 35-in. bunk and full roof fairing with side extenders.

The big one, the 82-in. Ultra High sleeper, is 13.8 in. higher than the original 82-in. Stratosphere and offers more than 30 cu ft of additional living and storage space. It allows for a fixed upper bunk that can be used in
conjunction with a dinette seating option. From ground to top of sleeper, it measures more than 13 ft, improving air flow over a standard 13-ft, 6-in. van trailer.

Options are many, including painted steel or stainless steel exterior sun visor; composite aluminum or severe-service galvanized steel cab floor; premium insulation; and automatic climate control.
