Winter Cover for Dometic Due Therm RV Air Conditioner  

Question:

Expert Reply:

Thanks for letting us help Richard. For your Dometic Duo Therm air conditioner, I'd recommend the Adco RV Air Conditioner Cover for Dometic Duo-Therm # 290-3021. This cover is specifically designed to fit your 57915 AC model. Unfortunately, none of the AC covers we carry are padded, but the # 290-3021 does have a soft felt interior that will help protect the exterior of your air conditioner from scratches. There should also be enough room to add some additional cushioning underneath the cover if you'd like a little extra protection.

One thing worth mentioning is that Adco recommends removing the cover before traveling or operating the air conditioner. These covers are intended for use while the RV is parked or in storage.

Are you getting your RV ready for winter storage, or are you planning to do some camping through the colder months?

I bought a couple of these for my RV and I was very impressed with the quality of these covers. There is a soft inner lining and it fits like a glove. Well worth the price.

@Lee Happy to hear that! Do you have Dometic Duo Therm's on your RV or are they different models?
