Hello Joe.

We do not have anything that would be a direct replacement with Atwood being out of business. I do have 2 different water heaters that I recommend.

First would be the Dometic RV Water Heater - Gas/Electric - Automatic Pilot - 120V - # DMC74FR. This water heater has a 6 gallon tank, 10,000 Btu, and requires a cutout of: 12-3/4" tall x 12-3/4" wide x 19-7/8" deep. You will also want to grab the Water Heater Door Conversion Kit for 6 Gallon Electric and Gas Water Heater - White # DMC84FR, your Atwood is a little larger than the Dometic, this would cover up that bigger cutout. For black use # DMC24FR.

Second option is becoming more and more popular, the Furrion RV Tankless Water Heater. This water heater is an excellent tankless option with 60,000 Btu, and requires a cutout of: Width: 12-3/4" to 12-13/16", Height: 12-5/8" to 12-3/4", Depth: Minimum 23-1/2". We have 3 different options for this water heater, you will need to choose according to what door size you need:

- 16" x 16" Door # FR98SR
- 16" x 18" Door # FR48SR
- 18" x 18" Door # FR68SR

I have also attached review videos of these products so you can get a good feel for them before purchasing.

Hey Joe, how did things turn out with the replacement for your Atwood water heater? Did you end up going with the Dometic model or one of the Furrion tankless options? Your update could make it easier for the next person facing the same choice.
