Dometic Ibis 4 vs Aircommand Ibis 3 Dimensions


Want to replace your existing Caravan Air Conditioner with an IBIS 4?


Replacing your existing air conditioner has never been easier with the IBIS 4 being able to fit into both, 360mm x 360mm and 400mmm x 400mm roof cut-outs. Currently, all RV air conditioners across all brands are made to suit these two sized cut-outs mentioned above. Not all RV air conditioners are made to suit both and having a unit that fits all existing apertures takes the hassle out of selecting the right air conditioner for your caravan.   

Check that you have enough space available on your roof!  Whilst the Ibis 4 overall length is physically like most other brand air conditioners measuring in at 1120mm in length, the slightly different mounting offset can make the Ibis 4 sit a further 100mm back (approx.) from where your existing similar sized unit currently is positioned.  Any solar panels or hatches that are mounted extremely close to the rear of your existing air conditioner may hinder the installation of your Ibis 4.  To be safe - allow an extra 200mm of space behind your existing unit.  To be exact - you need 840mm minimum clearance measured from the centre of your roof cut-out rearward of free space.

Ibis 4 rooftop air-conditioning

By: on 7 January 2021

There was a bit of a mix up with the aircon, it said in stock on website when I bought it but was contacted a few days later saying that they were out of stock, long story short I was keeped in the loop and it turned up earlier than expected, the installation was easy and I did it myself, I used a H frame as I put it on my 1985 poptop van, pump's out realy cold air and even keeps up on a 42 degree day, my 2200kw Honda jenny loves it, if I had to dis on something it would be the control of the out side condensation, I wished there was just one drain hole so you could put a hose on it and keep it off the roof,

We recently purchased the ibis 4 to replace our loud old ibis 2. We couldn’t be happier with our purchase , the ibis 4 is as quiet as our split systems in our house. There’s no start up shake & we can finally ditch the ear plugs. The service and delivery from Caravan RV was brilliant.

IBIS 4 Caravan Air Conditioner

By: on 29 November 2020

Very happy with this latest iteration of the IBIS, it is very quiet and easily handled the high temperatures we experienced during our recent trip through rural NSW, Goulburn, Bathurst, Mudgee, Gunnedah, Barraba, Yetman, Inglewood, Leyburn and Coominya. Most days were 39c from Mudgee north. So compared to our old IBIS it was money well spent. Installation was a beeze, old one off and new installed and christened in less than half a day with use of a borrowed wind up material lift, a ladder and two mates for muscle. Two very happy campers here!! And I did run it with my Yammy 2kva gen no dramas didn't affect the gen rpm to any great extent compared to brides hair dryer.

  • We have an older model ibis Mkll and are looking to upgrade to a new unit after feeling the heat this summer whilst on our holiday break, we have noticed the new Aircommand Ibis MK4 is now available and the unit looks fantastic. Just wanting to know if it will fit in the same size hole in our roof? Is it a direct replacement for previous models? Many thanks in advance.

    Hi There, yes, the new Ibis Mk4 has taken the RV market by storm.

    There have been multiple upgrades to the unit which intern is leaving the rest of the rivals in its wake. The Ibis Mk4 has a integrated adaption kit to suits existing apertures 400 x 400mm or 360 x 360mm there for making it a suitable replacement for all previous models of the Ibis and almost every RV air conditioner on the market.

  • Hi, I have an Aircommand sparrow installed on my full height caravan and is over 8 years of age. I'm wanting to upgrade to a bigger more powerful unit but still want to keep a sleek low-profile design as I don't have much room to fit under my garage. Is the Ibis MK4 a low-profile design?

    Hello, Yes, the Ibis Mk4 is one of the most low-profile sleek designs on the market. The total height of the unit is 230mm making it only 15mm higher than your Aircommand Sparrow, fingers crossed for you and hope this suits.

  • Hi, we have an old Dometic roof top air conditioner on our caravan and are interested in the Ibis Mk4. What is the overall installed weight of this unit? As we are right on the border with our weight levels as it is.

    The total installed weight of the Ibis Mk4 is 40Kgs, 8Kgs lighter than the previous model which means every little bit to its user as the authorities are cracking down on road users who are overweight with their caravans, trailers etc.

  • Hello, I own a pop top caravan and am very interested in the new Dometic Ibis MK 4. I have already purchased the H-frame to suit and was just wondering if this unit will still fit my roof thickness as the H-frame nearly doubles my roof thickness. Any ideas would be greatly appreciated?

    Hi, great question, the Ibis MK 4 accommodates roof thicknesses from 20mm - 100mm. If your roof thicknesses goes beyond 100mm you will need to purchase an Extension Duct Kit - Ibis MK4, for every 10mm over you will need one duct per every 10mm.

    I hope this helps and thank you for your enquiry.

  • How often do I need to service my Dometic RV/Caravan appliances?

    Dometic recommend servicing their gas appliances on a yearly basis, even if the vehicle has not been used.

    Additionally, bear in mind that insects can built nests in the gas appliances which will cause the appliances to stop working. It can also cause potentially dangerous scenarios.

    For other appliances, such as refrigerators and air conditioners, to ensure the appliances to work efficiently and last longer it is recommended to clean the condenser.
