• 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 Multiple Coleman Mach AC Units Be Controlled By Wireless Thermostat In RV?
  Hey Brian! Yes, the WiFi Thermostat # CM46MR will work with the new ducted Coleman-Mach units like # CM52RR, # CM65RR, # CM83RR, and # CM95RR. Since those are the ducted kits that already use a wall thermostat, that’s where this add-on thermostat makes the most sense. If you want, tell me what RV you have and how many AC units you’re planning to run. And just to be sure, the ducted units are for RVs that have AC vents in the ceiling that carry air through the coach. If your RV does not...

• 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...

• 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...

• Replacement Air Conditioner That Holds Up Better In Travel Trailer That Goes Off-Roading A Lot
  Hello Cole, for that kind of use, I’d recommend the Coleman-Mach Roughneck Mach 15 # CM65RR. If your air is routed through ceiling vents, you’re looking at the right style, because this is for ducted RV systems only. This does allow air to come out of the distribution box in the ceiling as well though, so that's a nice benefit of this model. The Roughneck line is the one I’d choose when the trailer sees more vibration and rougher travel than a normal campground setup. Since you asked...

• 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...

• 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...

• Looking For Complete AC System For Older Camper 5th Wheel Trailer That Had Ducted Vents
  Hey Chris, for a 31-foot fifth wheel in the South, I’d lean toward a 15,000 Btu system, and in this group that would push more toward the Roughneck Mach 15 # CM65RR if you want the extra cooling capacity. If your old unit struggled in summer heat, moving up makes sense. Since you mentioned ceiling vents, it sounds like you have a ducted setup, and these Coleman kits are for ducted RV systems only. If your old unit kept up pretty well and you’re just trying to make a smart replacement,...

• 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...

• Is There A New Coleman AC Unit For Toy Hauler That Gets Bounced Around On Rough Roads?
  Hey Melissa, for a toy hauler that sees rough roads regularly, I’d recommend the Roughneck Mach 15 # CM65RR first. That’s the tougher ducted option in this group, and it’s built with the reinforced construction that makes more sense for harsher use. If your toy hauler has cooled air routed through ceiling vents, then you’re in the right category because these are for ducted RV systems only. If the air only blows out of the ceiling assembly right at the unit, that would be ductless instead....

• Is It Better To Replace RV AC Unit Or Replace Entire System With Thermostat?
  Hey Mark, at around 10 years old, I’d usually recommend replacing the whole system instead of just the rooftop unit. These newer AC kits use R32 refrigerant, and the newer AC parts aren’t backward compatible with older systems, plus replacement parts for the older refrigerant setups are getting harder to find. If your trailer has a ducted setup with ceiling vents throughout the coach, a complete system like the Roughneck Mach 3 # CM95RR or Roughneck Mach 15 # CM65RR is the cleaner long-term...

• Which Coleman Mach AC Unit Is Going To Stay Together On Toy Hauler On Rough Gravel Roads?
  Hey Melissa, in your case the Roughneck Mach 15 (15k btu) # CM65RR is exactly the one I’d be looking at. The big difference between that and the Signature Mach 15 (also 15k btu) # CM52RR is the tougher reinforced construction on the Roughneck unit. That model is built around harsher use where more vibration and rougher travel are part of the job. It sounds to me like the Roughneck version makes a lot of sense for you since you travel gravel roads a lot. If you were just doing normal highway...

• Complete RV Ducted AC System For Lifted Off-Road RV That Sees Rough Roads
  Hey Melissa, for a toy hauler that regularly gets dragged down rough roads, I’d recommend the Coleman-Mach Roughneck Mach 15 # CM65RR. That’s the one in this ducted lineup that really fits the way you’re using the trailer. It gives you the full ducted setup with the rooftop AC, air distribution box, and wall thermostat, but the big advantage is the reinforced construction for harsher roads and more vibration. If this were mostly normal highway and campground use, I’d point you more toward...
