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 that off your plate. The rooftop unit, air distribution box, and thermostat 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 in one kit makes everything less stressful.

Consistent Cooling for Every Vent

This system moves air through your ceiling ducts to bring the temperature down quickly and evenly throughout the space without blasting you in the face or leaving dead spots near the bed. Large evaporator and condenser coils with raised lance 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.

Easy, Accessible Control at the Ceiling

The air distribution box gives you control right at ceiling level. Open the louvers for direct cooling into the cabin, or close them to push air through your ducts. The slim, low-profile design leaves you with more overhead clearance inside, and the swing-open grille makes it easy to reach and wash the filter. No tools required. Just pull, rinse, and snap it back into place.

Add Heat for Chilly Mornings

Sometimes its not cold enough to run the furnace, but its 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. Its easy to install and helps your space warm up without the noise or power draw of a full furnace cycle.

I’ve ordered many things from trailer and they have never let me down. Easy to order, fast shipping, right on time. Actually, it arrived a day early. Nice surprise.



by:

Product arrived in 2 shipments. Upon arrival checked for damage. None noticed. Upon removal from box found small crack in cover at bottom not far from screw attachment. Most likely from shipping. This was cosmetic and would not effect function of unit. Installed unit wired and tested. Temperature reached 67 degrees in rv in about 4 hours. Much better than the 98 degrees prior to installation.

  • 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...

  • Can Coleman Mach AC Replace Dometic AC on 2016 5th Wheel Trailer
    Hey Jeff! The Coleman-Mach Signature Mach 3 can replace the old Dometic AC on your 5th wheel. Since these are new R32 units and that will be an old R410A AC complete replacement is required. You can choose from the following based on the color you want and if you have a ducted/ductless setup: -Coleman-Mach Signature Mach 3 RV AC System - Ductless - 13,500 Btu - Textured White # CM38RR -Coleman-Mach Signature Mach 3 RV AC System - Ductless - 13,500 Btu - Polished White # CM58RR -Coleman-Mach...

  • Looking For A Replacement AC Unit Only For My Current
    Hey Jerry, Unfortunately there was a change in EPA regulations meaning anything 2024 and earlier is not compatible with new replacement units. We do not carry an exact replacement for your Coleman so you would need to replace the whole system. There may be a chance if you give Coleman a call they have a direct replacement that could be compatibly with your system still. Since we do not have a replacement I recommend going with a new Advent Air system, # ADV23SR. A 13,500 BTU unit that...

  • Is It Easy To Replace Old RV AC Unit With Complete Kit From Coleman Mach?
    Hey Jared, these are about as straightforward as a full AC replacement gets because they’re complete matched systems. You will however need to hardwire the ac unit into the old wiring, as you would with any ac unit. So whether you go with the Coleman-Mach Signature Mach 3 # CM83RR or Coleman-Mach Roughneck Mach 3 # CM95RR (for more off-road use), you’re getting the rooftop unit, the ducted air distribution box, and the wall thermostat together. You’re not piecing parts together from different...

  • Which AC Units Are Going To Draw Lowest Amperage For Off-Grid Camper With Generator?
    Hey Steve, these all run on 115/120V AC power, and the draw depends on the model and conditions. The Signature Mach 3 # CM83RR is listed at 12.8 amps in mildly warm weather (85 degrees F), and the Roughneck Mach 3 # CM95RR is the same size and amp draw. On the 15,000 Btu side, the Signature Mach 15 # CM52RR and Roughneck Mach 15 # CM65RR are both listed at 13.9 amps draw in the same weather conditions. These are among the most efficient, lowest amp units out there. So there is a little...

  • Deciding Between Ducted AC Unit 13,500 BTU Or 15,000 BTU Coleman Mach In 2019 Keystone Cougar
    Hey Aaron, if you’ve got ceiling vents spaced through the trailer that carry the air away from the AC opening, that’s the big clue you have a ducted setup, and these Coleman-Mach systems are for ducted RV units only. A quick way to double-check is to look at your current ceiling assembly. If the main AC ties into a network of ceiling ducts and vents instead of only dumping air right at the unit, you’re in the right category for the ducted units like Signature Mach 3 # CM83RR or Signature...

  • How Do I Know If My RV Has Ducted Or Ductless Air Conditioner System? Which New Coleman Unit Fits?
    Hey Jared, that’s a really smart question because “ducted” and “ductless” gets tossed around a lot. In plain English, ducted means the AC feeds cooled air into ceiling ductwork that carries that air to vents throughout the RV. Ductless means the air blows right out of the inside ceiling assembly at the AC itself instead of traveling through ceiling ducts. A quick check is to look around your ceiling. Since you said you have several vents throughout the RV ceiling, you’re ducted. If there...

  • Do New Coleman Mach AC Units For RVs Blow Air Through The Duct Vents?
    Hey Kevin, these Coleman systems are for ducted RV units only, so the first thing to check is whether your current setup sends air through ceiling ducts and vents throughout the RV. If you’ve got multiple ceiling vents away from the AC opening, that’s usually your answer. If the air just comes straight out of the inside ceiling assembly at the unit and nowhere else, then that would be a ductless setup instead. Assuming yours is ducted, the nice part is that these Coleman-Mach ducted systems...

  • Which AC Unit From Coleman Is Good For Boondocking With Generator?
    Hey Steve, that’s exactly the right way to think about it. If your RV is ducted and your old system cooled reasonably well most of the time, I’d probably go with the Signature Mach 3 # CM83RR instead of automatically jumping to a 15K unit. If your current AC was always struggling, then the Signature Mach 15 # CM52RR becomes the better recommendation. But if you’re mainly trying to make a smart full-system replacement, the Mach 3 may be the better fit for how you camp since it draws about...

  • Which Air Conditioning Complete System Including Thermostat Is Good For Smaller Travel Trailer?
    Hey Derek, not necessarily. If your fifth wheel is on the smaller side and your old system cooled well enough most of the time, I’d start with the Coleman-Mach Signature Mach 3 # CM83RR. It’s still a complete ducted system with the rooftop unit, ducted air distribution box, and wall thermostat. It still does a great job of cooling most RVs. I’d only jump to the Signature Mach 15 # CM52RR if your old AC was always behind the curve in summer heat and you already know you need more cooling,...

  • AC Unit Complete Kit With Heat Strip For Chilly Mornings - RV With Ducted AC Vents In Ceiling
    Hey Cheryl, if you want a comfort-minded setup, I’d recommend either the Coleman-Mach Signature Mach 15 # CM52RR or the Signature Mach 3 # CM83RR, depending on the size of your RV and how hard your current AC has to work in summer. Then I’d pair it with the optional heat strip # CM96RR. That gives you a complete ducted AC replacement for summer, plus a little electric heat to take the chill off on cool mornings. I just wouldn’t treat the heat strip like a furnace replacement. It’s more...

  • Will Heat Strip Help In Chilly Weather Camping Using Coleman Mach AC Units?
    Hey Cheryl, I’d think of the Coleman heat strip # CM96RR as a comfort add-on, not a true furnace replacement. It’s a great option if you want to take the chill out of the cool mornings, but I would not count on it to do the same job as your RV furnace in genuinely cold weather. That applies across the ducted systems you’re looking at, including units like the Signature Mach 15 # CM52RR, Roughneck Mach 15 # CM65RR, Signature Mach 3 # CM83RR, and Roughneck Mach 3 # CM95RR. It’s a nice upgrade...
