Hi my name is Robert.
I do not think there is any difference between them, normally they go by the first numbers which is the gc10A-4e, it is a 10 gallon gas/electric water heater. All the parts will be the same for both. Robert
So there are some different options, something I just learned, click HERE and you will see what features each has.... Robert
It looks like one has a heat exchanger and one does not, heaters with heat exchangers transfer otherwise wasted energy from the engine-cooling system of a motorized coach to the water heater during travel.... Robert
