Switching to a tankless water heater to replace your Atwood GC10A-4E is a really smart idea and the best option to replace it is from Furrion:

- Furrion RV Tankless Water Heater - 18" x 18" Door # FR68SR

The # FR68SR will fit easily in the cut out of your GC10A-4E because it is smaller (12-5/8" wide x 12-5/8" tall x 19-1/4" deep compared to your Atwood's 16" tall x 15-1/2" wide x 20-7/8" deep) though you'll have to resize the height of the door cut out. The Atwood door is just 10" tall and there are no heaters nowadays that have such a short opening, which is why the resizing is necessary.
