Many older Atwood water heaters have been discontinued, the most straight forward replacement for yours currently is the Dometic RV Water Heater - Gas and Electric - Automatic Pilot - 120 Volt - 10,000 Btu - Item # DMC74FR. This is a 6 gallon gas/electric like you currently have with an automatic pilot. This uses 120V power and comes with the switch panel to operate it. The Double-Panel On/Off Switch # AT91230 will allow you to power the electric and gas components on and off individually. It mounts in your coach for easy operation.

If you prefer to replace with a tankless, we have the Fogatti RV Tankless Water Heater with automatic pilot at 41,800 Btu in black, # LSB44FR and a white door in # LSB44FR. The overall dimensions for this unit is 14-3/8" long x 15" wide x 15" tall requiring a cut out dimensions of 13" wide x 13" tall x 17-3/4" deep. The access door is 14-15/16" tall x 14-15/16" wide.

We also have, my preferred option due to 60,000 BTU rating, the Furrion RV Tankless Water Heater, # FR93FR. The overall dimensions are 19-3/16" deep x 12-5/8" tall x 12-13/16" wide.
