What is a Sleeper Cab?

A sleeper cab is a space located behind the driver’s area of a semi-truck that typically contains at least a bed and, depending on the level of finishing, other amenities, such as a bathroom, fridge, work station, microwave, TV and so on. Sleeper cabs let long haul truckers sleep in their trucks instead of at a motel, allowing them to meet off-duty time requirements in a convenient and affordable way.

What Amenities Are Included in a Sleeper Cab?

A sleeper cab will always include a bed, but may include other amenities such as a closet, small desk, refrigerator, microwave, and TV. You also have the ability to get an inverter and multiple outlets for power. Storage is often at a premium in sleeper berths, so many have built-in and efficiently designed storage spaces.

Some models also offer red floor lighting or ambient ceiling lights. This allows the driver to have dim lights on without affecting visibility and without lighting up the cab interior.

As for the actual sleeping space, you have several options, including your basic single bed, a larger bed that can fit two people, or even bunk bed options. Manufacturers are constantly trying to make sleeper cabins more comfortable. For example, Volvo offers a reclining bunk option with adjustable positions, which can provide an easy chair feel to your bunk. They also offer USB and 12-volt charging ports for top and bottom bunks

For entertainment, you can have gaming consoles in your sleeper cab or even in-cab satellite TV through providers like EpicVue.

How Much Does a Sleeper Cab Cost?

The price of a brand new semi truck with a sleeper cab from a reputable manufacturer will run between $230,000 to $280,000, depending on the make, model, size, configuration and level of amenities you choose.

If you are just looking for the sleeper cab, you can expect to pay on average around $55,000 for a new one, although that too will vary widely on your level of finishing and customization, etc. Source

Used sleepers can cost significantly less, so that may be an option worth exploring. You can find used sleepers on sites like Usedvending.

What Are the Most Popular Brands of Sleeper Cabs?

Among the major manufacturers of semi-truck sleeper cabs are Volvo, Freightliner, International, Peterbilt, Kenworth and Mack.

As you probably already know, these are major names in the trucking industry and each have solid reputations (although admittedly they have their respective strengths and weaknesses).

But I will not digress into all that. Below is a table listing out some of the most popular brands of truck sleeper cabs and key information for each. Note: Not all sleeper cab models are listed for each brand.

BrandModelPrice (New)Distinguishing Features
Volvo VNL SeriesApprox. $230,000Integrated reclining bunk and robust sleeper control panel.
FreightlinerCascadiaApprox. $230,000Generous storage and closet space and room for larger appliances
PeterbiltModel 570Approx. $235,000Largest mattress in industry, 8 ft headroom clearance, 70 cubic feet storage
KenworthW900Approx. $270,000High end truck offering handcrafted appointments in the interior

Ok – we’ve got the numbers out of the way. Sleepers are not cheap, for sure, but as mentioned earlier, you can save a lot by buying used.

How Large Are Sleeper Cab Interiors and Beds?

The dimensions of a semi-truck sleeper cab vary widely. Cabin widths generally match the width of the truck, while heights and lengths run across the board, with some low roof models measuring less than 6 feet tall and high roof models that can clear 8 feet. Lengths vary even more, with some customized extended sleeper cabs that can be over 200 inches long.

Bed sizes in sleeper cabs also vary, but generally, Peterbilt and Kenworth have a reputations for offering larger bed sizes. That being said, in most cases, bunks come in a standard twin XL or “long twin” which means that even if you are fairly tall (over 6 feet), you should be able to sleep in relative comfort.

Now, there are some sleeper cabs that are so large, they almost defy logic. These are almost always fully customized builds, but these giants of the road can span far beyond even 200″ and often have really unique features, such as a garage space for motorcycles.
