Hello Pamela, thanks for reaching out. Our best option for replacing your Atwood GC6aa-10e water heater is the Furrion RV Tankless Water Heater # FR98SR. This fits into a 19-3/16" deep x 12-5/8" tall x 12-13/16" wide cutout and has a 16"x16" door. There is no direct replacement available for the GC6aa-10e so going tankless is what we recommend. You may have to modify your cutout to make it fit is the only thing. This unit is available with an 18" door, part # FR68SR if you need a larger one.

Hey Pamela, how did the switch to the Furrion tankless water heater go as a replacement for your old Atwood unit? Were the cutout changes manageable? Your update could make it easier for others facing the same upgrade.
