Expert Reply:
Hey Nancy, there is no direct replacement for the Atwood GC10A-3E so I'd recommend going with the Fogatti InstaShower 7 RV Tankless Water Heater # FG46FR. This is a tankless unit, measures 14-5/16" long x 18" wide x 18" tall, and has a 48,000 Btu heating capacity.
This is quite a nice upgrade as well, being tankless an all. Now, you and your family or whomever, can get nice hot water on demand, which is super convenient on super cold days like what we're dealing with here in Missouri!
