Features to know about

Cools Large Spaces Fast: 15,000 Btu of Steady Output

This setup brings real cooling power when the temperature climbs. The 15,000 Btu rooftop unit pushes strong airflow through the ceiling ducts, dropping the heat quickly and keeping larger interiors comfortable. It runs on 12V DC with a cooling amperage of 13.9 amps and uses R32 refrigerant to meet 2025 EPA regulations, so it’s efficient while keeping performance high.

Keeps Comfort Consistent: Ducted System with Adjustable Louvers

The ducted design moves cool air evenly through your vents, but you can also open the louvers on the air distribution box to get direct airflow right where you are. It’s an easy way to fine-tune comfort without extra gadgets or remotes. The slim box keeps overhead space open, and the EZReach filter system makes cleaning quick—just pull it down, rinse it, and snap it back in.

Simplifies the Upgrade: Matched Components That Work Together

Figuring out what pairs with what can be a pain. This complete kit takes care of that by including a rooftop unit, air distribution box, and single-zone digital thermostat made to work together. Everything lines up with the standard 14-1/4" × 14-1/4" roof opening for a smoother install and dependable operation once it’s in place.

Adds Warmth When You Need It: Heat-Ready Design

When mornings feel a little too cold for comfort, this system is ready for an optional 5,600 Btu heat strip (sold separately). It’s a simple add-on that brings gentle warmth without firing up a furnace or pulling heavy power. With cooling and heat capability in one setup, it keeps your space livable across more seasons.

Built to Last on the Road: Durable Construction with Backed Warranty

The textured white rooftop unit stands up to weather and vibration while holding its seal season after season. It measures 39" long × 26" wide × 13-1/2" tall and weighs 85 lbs. The air conditioner carries a 2-year limited warranty, and the air distribution box and thermostat each have a 1-year limited warranty—coverage that shows it’s made to keep going trip after trip.

Haven’t installed yet but the product came in properly.
Thanks

E-trailer is the place to buy delivery purchasing everything all good the Coleman air conditioning rooftop no problems simple to install and works great



by:

The units were in great shape as they were delivered. when I was putting in my order the screen said Sunday delivery, when I submitted the order it changed to Monday, when I tracked the order it said Tuesday. It was Tuesday that it was delivered. that is the only negative thing about my order. everything else is as ordered. I did not realize I ordered the units with the control knobs but that was my mistake. I really needed the ones with the thermostat controls. If there is a kit to switch it from the knobs to the thermostat I would love to know what it is.

Excellent customer service and proper, product knowledge!



by:

We received the air conditioning system quickly. I had only one issue with one of the brackets. It was bent on arrival but I was able to bend it back into shape. We installed the unit and it works great!



by:

Came slightly damaged but nothing that couldn’t be straightened. Unit works very well. It was certainly a positive upgrade

  • Replacement for Coleman-Mach AC on Travel Trailer
    Hey Kyle! You can replace your old Coleman-Mach AC with one of the new ones. However, you will need to replace the thermostat and air distribution box as well. All of the new AC units use R32 refrigerant following the 2025 EPA guidelines so any old R410A components aren't compatible. We have 13,500 Btu or we have the 15k units if you want to upgrade. You can choose from the following based on color and ducted/ductless: -Coleman-Mach Signature Mach 3 RV AC System - Ductless - 13,500 Btu...

  • Difference Between Coleman-Mach Roughneck Mach 15 and Signature Mach 15
    Hey Bill, great question! The Signature Mach 15 is your standard AC unit which is probably what you want. The Roughneck has a fortified interior making it ideal for off-road and heavy industrial vehicle applications. Basically it is made to take more of a beating. If you had an old carrier and it is wearing out from use over time (I'm guessing that is the case here) the Signature is what you want. If you have been off-roading with your trailer lately and it killed off the Carrier then...

  • Can Furrion Chill HE Replacement AC Replace Coleman Mach 8 in 2020 Vanleigh Beacon
    Hi Jake; the Furrion Chill HE Replacement RV Air Conditioner for Coleman Setup # FR32PV is an old kit that is on its way out. We no longer recommend replacing just the AC unit, and can't guarantee this will work as a plug and play replacement. We have had customers in the past successfully swap them out, others have found the connector doesn't work, sometimes the systems don't work together, and occasionally mixing up the AC with other components burns out the air distribution box (ADB)....

  • How Does Coleman Mach 15 Compare to Furrion Chill Cube
    THey Brian, the Coleman Mach Signature Mach 15 part # CM32RR is a really solid AC unit. As far as how it compares to the Furrion Chill Cube # FR69TD it only has the advantage of working more consistently with furnace controls. Aside from that the Chill Cube wins in terms of cold air blowing, quietness, and amperage draw. If you'd be open to it the best setup would be a Chill Cube and then a furnace only thermostat like the part # DMC84RR. Does running a second thermostat work for you at...

  • Adding 3rd Coleman-Mach AC to Ductless Setup With High Ceiling
    Hey Mike! Since the ceiling controls on the # CM43RR would be too high to reach you can use the Coleman-Mach Signature Mach 15 RV Air Conditioner System # CM32RR with the wall thermostat. This is the ducted version, but the AC itself is the same with the ADB and thermostat being the difference. You can simply leave the louvers open so it dumps air directly into the room. Since the systems aren't tied together, you could also add an AC like the Furrion Chill Cube # FR59TD. This operates...

  • Can Coleman-Mach AC Replace Dometic Duo-Therm on 2014 Forest River Travel Trailer
    Hey Earl! Yes, the Coleman-Mach Signature Mach 15 AC system can replace your old Dometic Duo-Therm. These are new R32 refrigerant units (everything is as of 2025) so a complete replacement will be necessary. You can choose from the following based on ducted/ductless and the color: -Coleman-Mach Signature Mach 15 Air Conditioner System - Ductless - 15,000 Btu - Textured White # CM43RR -Coleman-Mach Signature Mach 15 Air Conditioner System - Ductless - 15,000 Btu - Polished White # CM93RR -Coleman-Mach...

  • Replacement for Coleman Mach 15 With Heat Pump
    Hi Brian! I would not try to repair a 14 year old AC. It is typically more cost effective to replace the system, and you may not even be able to get parts depending on what went wrong. R410A units have been phased out as of last year because of EPA guidelines so nobody is making parts for those systems. Since everything moved to the R32 refrigerant complete replacement will be required. If you want to stick with Coleman-Mach, and have a ducted system, the Coleman-Mach Signature Mach 15...

  • Heat Strip for Coleman-Mach Signature Mach 15 RV Air Conditioner System
    Hey Mike, welcome back! The correct heat strip for the Coleman-Mach Signature Mach 15 # CM32RR is the Electric Heater Kit for Coleman-Mach Medium and Low-Profile RV Air Conditioners # CM96RR. There is an empty location in the ADB to mount it, and then it plugs right in with that 2-prong connector. You won't have to hardwire anything. Any big trips coming up once you get the 3rd AC installed on your Montana?
