Features to know about

A Matched Kit That Simplifies the Install

One of the biggest headaches in RV repairs is figuring out which parts are compatible. This kit takes all that off your plate. The rooftop unit and air distribution box are made to work together, so installation is smoother and nothing catches you off guard. Whether you're doing the install yourself or paying someone else to do it, having everything designed as a set makes the job faster, cleaner, and less stressful.

Consistent, Ductless Cooling

If you've ever had an AC that ran all day and still left the rig feeling muggy, this one's a different story. It's made for RVs without ducted air, so it's perfect if you're replacing an old setup or adding a second unit to cool a separate space. And with 15,000 Btu of cooling power, you'll feel the temperature shift within minutes, not hours. Inside the unit, large coils and airflow-boosting fins help pull heat out efficiently, so your RV stays cooler with less strain on the system. You walk in, and the air feels dry, cool, and breathable - like a good night's sleep is actually possible again.

Easy, Accessible Control at the Ceiling

The air distribution box gives you full control right at ceiling level, with simple knobs you can reach without digging for remotes or climbing over furniture. You can direct airflow where you need it with adjustable dampers, and the low-profile, Euro styling helps cover old ceiling imprints from earlier setups. When the filters need cleaning, the pop-out grilles make it easy. No tools required. Just pull, rinse, and snap it back into place.

Add Heat for Chilly Mornings

Sometimes, it's not cold enough to run the furnace, but it's too chilly to be comfortable. This system is prepped for a 5,600 Btu heat strip (sold separately), which is a simple way to take the edge off on those in-between mornings. It's easy to install and helps your space warm up without the noise or power draw of a full furnace cycle.

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.

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

  • 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 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...

  • Adding AC Unit To Horse Trailer Build - Ductless Where Air Blows From Ceiling Unit
    Good morning Malik, for a new ductless install I’d look at the Coleman-Mach Signature Mach 15 # CM73RR. It’s a complete 15,000 Btu system, so it includes the rooftop unit and the matching ceiling air distribution box. You’ll get simple ceiling controls and direct airflow without needing ductwork. It also fits the standard 14-1/4 inch x 14-1/4 inch AC roof opening and can use the Coleman-Mach heater kit # CM96RR if you want light electric heat later. Are you cutting a new opening, Malik,...

  • AC System For Small Travel Trailer With Electric Heat Strip For Fall Weather Camping
    Good morning Tomas, I’d go with the GE Appliances Deluxe Plus # GE34RR for that. It’s a complete ductless 15,000 Btu system, so it includes the rooftop AC, air distribution box, thermostat, and controls. That's plenty of cooling capacity for a smaller camper. It also has the heat pump built in, which is nice for cool mornings when you’re plugged into shore power and don’t want to fire up the propane furnace. Just remember this is the ductless kit, so it’s for RVs without ceiling AC vents....

  • Adding Second AC Unit To Garage Area Of 5th Wheel Toy Hauler That Is Already Pre-Wired
    Good morning Briar, the Coleman-Mach # CM73RR would work well for that kind of separate garage AC setup if you want a complete ductless system. It includes the 15,000 Btu rooftop unit and the matching air distribution box, so it can be controlled right at the ceiling instead of tying into your front thermostat. That makes it a clean option for toy hauler garages, bunk rooms, or other separate spaces. It fits a standard 14-1/4 inch x 14-1/4 inch roof opening and can use the Coleman-Mach...

  • Standalone AC Kit For Rear Garage Bay Of Toy Hauler That Has It's Own Manual Controls, No Thermostat
    Hey Soren! Yes, the Coleman-Mach # CM73RR makes a lot of sense for that kind of separate rear-bay setup. It’s a complete ductless 15,000 Btu system, so it includes the rooftop AC and the matching air distribution box with controls right at the ceiling. That means it does not need to tie into the thermostat for the living quarters. As long as that rear area has the proper framed roof opening and wiring for an AC, this gives you a self-contained cooling setup for that space. It's also a...

  • Camper AC System That Has Cleanable Filters For Good Airflow Year Round
    Hey Juno! The Coleman-Mach # CM73RR would make sense if your camper is ductless and you want a complete 15,000 Btu system with easy ceiling controls. The included air distribution box has pop-out grilles, so cleaning the filters is pretty simple when dust, pollen, and tree debris start adding up. It also has front and rear dampers so you can aim airflow where you want it instead of just blasting one spot. This is a complete ductless system, so it’s best for RVs without ceiling ductwork....

    Hey Luis! The Coleman-Mach # CM73RR is the full ductless 15,000 Btu system, so it’s a strong option if you’re cooling one open area and want direct airflow from the ceiling assembly. It includes the rooftop unit and matching ductless air distribution box, so you won’t need to piece together the ceiling controls separately. You also won't need to run wiring for a thermostat since it's all contained inside the ceiling controls :). For a smaller camper, 15K Btu can be a lot of cooling, but...
