Hey Keith, thanks for the information! The Dometic RV Water Heater item # DMC74FR is going to be our closest replacement option. Your GCH10A-4E has both gas and electric features and a heat exchange that connects to RV's radiator system.

The Dometic item # DMC74FR is a 6 gallon water heater that works with both gas and electric. It fits in a 12-3/4" tall x 12-3/4" wide x 19-7/8" deep cutout. You'll also need the 15" x 15" Replacement Door for Dometic and Suburban RV Water Heater item # DMC58FR.

Please note that the Dometic item # DMC74FR will not connect to your RV's radiator. We do not carry ones that do.

Are you interested in a tankless option? A tankless water heater like the Furrion item # FR93FR produces up to 144 gallons of hot water per hour versus the 12 gallons per hour the item # DMC74FR provides.
