57X SLEEPERS & INTERIORS

STRETCH YOUR LEGS WITHOUT EVER STEPPING OUTSIDE.

While most interiors out there feature sleepers that seem little more than afterthoughts, Western Star’s all-new interior is planned with comfort, space and storage to spare. With four sleeper models, five roof heights and a high-quality walkthrough design, you can outfit your truck exactly how you want. Add to that a variety of ugraded material and color options and you have the kind of workplace you’ve always wanted. After all, it’s your truck. It should fit you, not the other way around.
