Get the Btu sizing that you need

Bigger isn't always better. Getting a furnace that's bigger than you need can cause problems. A major one is that it will burn even more propane than you need.


You really only need about 1,000 Btus for every foot of RV length. For example, a 20,000 Btu furnace would be good for a 20' trailer or motorhome. That's why we'd recommend this one for a 40' trailer.


Door or doorless?

If you're installing a new furnace, the decision between door or doorless furnace will depend on where its installed and how you can get to it for maintenance or repair. With a doorless version, only the vent plate will be visible on the outside of your RV. This gives you a cleaner look, but it also means that you must be able to access the furnace from the inside of your RV.


The doored version isn't really a door, but more of an access panel that is screwed in place. You shouldn't need to access your furnace regularly, but when you do, you will need that access panel if the furnace is mounted in a place that you can't easily get to inside your RV.

It works as well as the original but was way overpriced. etrailer service was excellent.

The flimsy sheet metal on one end was slightly bent when I received it, but that was no issue. The unit installed quickly it was the correct item and is performing fine.

  • Replacement for AFMD35121 Furnace in 2018 Keystone Cougar 27SAB
    Hi Harvey; the DFMD35 series (same as your AFMD35121) has been discontinued. This leaves you with two options. You can either downsize to a 30k Btu unit or move up to the 40k unit. The 30k will fit in your existing space but you will have a little less heat. If you go up to the 40k unit it will probably require enlarging your opening since it is 2" taller. You also need to match door for door or doorless for doorless when choosing the replacement. The 40k units measure 20" deep x 9" tall...

  • Will the Dometic RV Furnace # DMC72ZR Replace My Dometic Furnace Model Number 942?
    Hello Justin, I believe that the # DMC72ZR is the same as your 942. Dometic Model 942 is likely an internal or legacy model number. The Dometic RV Furnace - Propane - Automatic Pilot - 12V DC - 40,000 Btu - Doorless # DMC72ZR is listed as 40,000 Btu, to ensure that it is a direct replacement you will just want to confirm the measurements: 20" deep x 9" tall x 16-1/2" wide. As for the cost, the Canadian standard at checkout will be the price to get it from our warehouse to your front...

  • Availability of Dometic 38362 Furnace

  • Looking For AC With Heat Pump, Bigger Furnace And Tankless Water Heater For 2025 Forest River Camper
    Hello Jay, sounds like you are somewhere cold and need to warm up! lol. Yes, the GE Appliances Deluxe Plus RV AC w/ Heat Pump # GE37FR is exactly what you will need. This will work with your current thermostat and controller so those would not need to be swapped out. You can do the rooftop unit only. As far as the furnace, we do offer replacements up to 40,000 BTU. For example, the Dometic RV Furnace - Propane - Automatic Pilot - 12V DC - 40,000 Btu - Doorless # DMC72ZR. This is 20"...

  • What Furnace do I Need to Replace My Atwood 8940-111-DCLP in My 07 Holiday Rambler?
    Hello James, To replace your Atwood 8940-111-DCLP, you will want to go with the Dometic RV Furnace - Propane - Automatic Pilot - 12V DC - 40,000 Btu Black # DMC48RR (or White Door # DMC68RR, or doorless # DMC72ZR). This is going to be your best replacement, the only difference on the size is this Dometic is 16 1/2' wide, and your current Atwood is 16". It matches your current 40,000 BTU rating, so you’ll keep the same heating capacity your Holiday Rambler was built around. It also runs...

  • Looking for Air Conditioner for RV to Replace Dometic that Has Heat Option
    Hey Scott, it sounds like you are looking for an AC unit that also has a heat pump built into it that can also provide some heat. For that the GE Appliances Deluxe part # GE85ZR would be a great option as this is a 15k btu rated system that has a heat pump built into it. Now heat pumps can provide a decent amount of heat but it's not equal to the amount of cold air they can provide so if you are looking for more a furnace might be a better option for providing the heat source like with...
