When the road turns rough and washboard trails shake everything loose, this system keeps its cool. The Coleman-Mach Roughneck Mach 3 is built with a steel coil housing, a reinforced basepan, and a stabilizer that ties the compressor and coil into a solid frame. It stays together through vibration, bumps, and jolts so you can travel the backroads without worrying about your cooling system rattling apart.
Heat builds up fast in tight spaces, but this 13,500 Btu setup moves enough air to turn that heat around quickly. It uses R32 refrigerant to meet 2025 EPA regulations and delivers steady airflow that drops temps within minutes. Because it’s non-ducted, the air flows directly from the air distribution box so the space feels dry, cool, and breathable from the start.
You don’t have to go hunting for a wall thermostat—everything’s right at ceiling level. The control knobs let you set fan speed and cooling directly on the air distribution box, while adjustable front and rear dampers direct air where you want it. When filters get dusty, the pop-out grilles pull free for a quick rinse and snap back in place without tools.
When mornings start cold or weather turns on you, this system can handle that too. It’s prepped for an optional 5,600 Btu heat strip (sold separately), giving you just enough warmth to take the chill off without firing up another heater. It’s an easy upgrade that keeps comfort steady through changing conditions.
Swapping out an old unit or building from scratch goes easier when everything fits together. This kit includes a medium-profile rooftop unit and a matching air distribution box designed to work as one system. With its 14-1/4" x 14-1/4" opening size and polished white finish, it drops in cleanly for a dependable setup that looks good and performs right from day one.
