AT Atlas Upfit

Continuing our tradition of designing purposeful high-quality equipment for overland travel, AT Overland Equipment reveals the all-new Atlas™ truck top camper. The Atlas™ provides a durable, insulated and lightweight vertical pop-up shell for today’s fuel-efficient trucks, while still leaving room for individual customization.  The Atlas™ sleeps two with enough interior room for one to stand when another person is in the bed. The Atlas™ can be deployed with 100 lbs. of cargo on the roof.

Filling the void between the traditional truck topper and slide-in camper, one person can easily open the cavernous and functional interior in 60 seconds. 6’ 10” feet of headroom is available under the insulated composite roof and is the only vertical pop-up topper on the market with a window on each of the four tent walls. The vertical pop-up provides more comfortable leg room in bed than wedge style toppers for taller occupants.

The 360 lb Atlas™ is made from the same lightweight aluminum and honeycomb composite as the proven Habitat and Summit toppers. This advanced construction provides insulation while adding strength and a surface that can be fitted with flush-threaded fasteners for attaching a variety of gear. Opening and closing is facilitated by robust gas springs and remains stable in event of high winds or snow loads. The locking rear liftgate and top-latches keep gear secure. Double pane acrylic windows and skylights are available to let light in and keep weather out. These Euro-style openings feature retractable bug screens and thermal curtains. For external gear access, upward-opening weathertight locking cargo doors are available.

The 48″x 80″ (the length of a queen size bed) two piece sleeping platform features a 2.5″ thick mattress. Out of the way when not in use, it is easily deployed when it’s time for bed. There is enough room between the sleeping platform and the closed roof of the Atlas™ to leave bedding in place, making the Atlas™ amazingly convenient to use and easy to deploy. With the sleeping platform in place, the remaining open standing area of 48″ x 38″ allows another person to move around in the truck bed or access the sleeping platform without disturbing the sleeper.

The Atlas™ features a durable FMVSS compliant canvas tent that is breathable and waterproof. For cold weather, an optional FMVSS compliant, light-blocking, Thinsulate™ liner is available with matching window openings and a R value of 1.4 (34º to 36º heat retention). This thoughtful combination of materials makes the Atlas™ a comfortable space, whatever the weather.
