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.
