The Mach 10 delivers full 13,500 BTU cooling in one of the lowest-profile rooftop shrouds Coleman builds -- just 11.8 inches tall. Less rooftop height means reduced aerodynamic drag, better fuel economy on highway runs, and more margin at low-clearance bridges and campground overhangs. Top-down mounting hardware is included so installation goes straight through the standard 14 x 14 inch roof opening.
Most RV rooftop ACs sit 13 to 16 inches above the roofline. The Coleman Mach 10 cuts that to 11.8 inches without giving up the 13,500 BTU output that owners of 30 to 40-foot rigs expect. The result is a unit that fits tighter height restrictions, feels more stable at highway speeds, and still keeps a large coach comfortable on a 100 deg F afternoon.
Part number 35203-0792 (vendor cross-reference 08-8596) is the black-shroud variant with top-down mounting. It ships as a complete condensing/evaporator assembly ready to drop onto the roof -- no separate shroud kit required.
One of the lowest rooftop heights in the 13.5K class -- less drag, more clearance.
Rated output for coaches up to approximately 40 feet. No reduction in power despite the compact shroud.
Installs through the standard 14 x 14 inch roof cutout from above. Mounting hardware included.
Color-matched finish for rigs with black or dark rooflines. Durable UV-resistant ABS construction.
Every inch of rooftop height adds aerodynamic drag at highway speeds. A taller AC shroud creates a larger frontal area that the engine has to push through -- translating directly into fuel consumption. The Mach 10 shroud is noticeably shorter than the standard Mach 8 or Mach 15 units, which is meaningful on long interstate hauls. It also helps when navigating parking structures, low tree canopies, or campground entrance gates with posted clearance warnings.
At 11.8 inches tall, the Mach 10 shroud clears campsites and low bridges that would require route changes with a taller unit. Owners report measurable improvement in highway fuel economy after swapping from a full-height replacement.
The Mach 10 uses a top-down installation method: the unit is placed on the roof, and the mounting bolts are driven down through the ceiling assembly from above, securing to the interior distribution box below. This differs from some older Coleman units that required someone inside and someone on the roof simultaneously. The included hardware fits the standard 14 inch x 14 inch RV roof opening used by most Class A, Class C, fifth wheel, and travel trailer manufacturers.
A foam gasket seals the rooftop flange to prevent water intrusion. Inspect and replace the gasket any time the unit is removed -- do not reuse a compressed gasket.
This listing is for the rooftop unit only. The interior ceiling assembly (distribution box, air diffuser, and thermostat/control interface) is sold separately. Verify that your existing Coleman Mach ceiling assembly is compatible with the Mach 10 series before ordering, or order a matched kit. Coleman Mach ceiling assemblies for the 10 series are available individually.
The Mach 10 35203-0792 is a direct replacement for aging Coleman Mach rooftop units that mount to the standard 14 x 14 inch opening. It is commonly used as a replacement on Class A motorhomes, Class C motorhomes, fifth wheels, and large travel trailers where the existing Coleman Mach 8 (48000 series) or earlier Mach 10 units have reached end of life.
This unit operates on 120V / 60 Hz AC power. It requires a dedicated 15-amp circuit at minimum -- do not share the AC circuit with other high-draw appliances during startup. Compressor startup draw is significantly higher than running amperage; undersized wiring or extension cords can cause tripped breakers or voltage damage. Confirm your coach wiring and generator output before installing.
