What Size Mattress Fits in a Mack Pinnacle?

Mack Pinnacle

All around, the Mack Pinnacle is a great sleeper truck for truck drivers who regularly travel long distances because it is specifically designed for heavy loads, steep grades, and long hauls. This truck comes in three configurations including a 48-inch flat top sleeper, a 70-inch stand up sleeper, and a day cab. The day cab is best suited for local trips while the 48-inch sleeper is ideal for overnight hauls. The 70-inch sleeper cabin is perfect for regional hauling because it is incredibly spacious. At the driver’s seat in the 70-inch sleeper, there’s a ceiling height of 6’11, and the rear cab offers a generous height of 7’1 so drivers can feel comfortable stretching their legs and walking. In addition to the roomy interior, there is plenty of additional storage, overhead compartments/bins, and oversized cup holders.

The Mack Pinnacle’s amenities include:

  • A stainless-steel refrigerator
  • 12-volt outlets for a microwave, tv, laptop, etc.
  • V-MAC IV system
  • Co-Pilot - an LCD monitor with more than 50 displays

Sleeper Environment

The Mack Pinnacle provides drivers with a whole new level of comfort having 35% more space than most other truck configurations. On top of the additional living space, you can use a sleeper control panel to control a sleeper stereo, interior lighting, and the HVAC system. The four-point cab lighting is not only the best-in-class, but it also reduces any dangerous glares. The Mack Pinnacle sleeper also keeps out disturbances with lightweight, high-tech sound deadening material to dull any outside noises, and built-in blackout shades for an added level of privacy and comfort when resting. The Mack Pinnacle even boasts a small workspace with a retractable table where drivers can eat meals, work on a laptop or relax while not on the road. Last but most certainly not least, the Mack Pinnacle offers a sleeping space for a 38-inch by 80-inch mattress.

Upgrading to the Right Mattress

The Mack Pinnacle conveniently comes with a traditional innerspring mattress, however, an OEM mattress usually only lasts so long. After some time on the road, many truck drivers find themselves needing a mattress upgrade – something that will provide more substantial support and better minimize motion transfer. Since finding the proper mattress for your needs and your sleeper cabin can be challenging, there are several things we highly suggest you consider before purchasing a new mattress. Price point, mattress size, and mattress quality are all very important to remember when looking for the perfect aftermarket mattress. With truck mattresses, in particular, it is crucial that you upgrade with the correct size mattress. In the case of a Mack Pinnacle, the sleeper bunk measures 38 inches wide and 80 inches long, which is large enough to accommodate a twin XL mattress. A twin XL mattress, or a truck mattress with similar dimensions, is perfectly sufficient for a tired driver since it provides the length of a traditional king or queen size mattress, but is compact enough to fit comfortably in a sleeper cabin.
