Hey Justin, thanks for stopping by! You can use the Dometic RV Water Heater # DMC74FR to replace your Dometic GC6AA-10E water heater.
This water heater is also a 6 gallon unit, like your current one, and requires a 12 3/4" tall x 12 3/4" wide cutout. You will need a bit more depth to get this to fit so you'll want to verify you have the correct amount of space first.
Feel free to come back and let me know if there is anything else I can do for you!
