Question:
The water heater is missing in my 2000 Winnebago Journey 34B. Parts catalog shows P/N GCH10A-3E. I believe that they are no longer available. Can you recommend a replacement. The vent is in the cargo bay door

Expert Reply:
Hey Fred! That is correct, the Atwood GCH10A-3E is no longer around since Atwood no longer exists. Assuming you want to move to a tankless, the Furrion RV Tankless Water Heater # FR93FR you were looking at is the best option. Since you have the 10 gallon Atwood the 18" x 18" door is the correct fit. You can choose from the following based on color:
-Furrion RV Tankless Water Heater - Gas - Auto Pilot - 60,000 BTU - 18" x 18" Door - Black # FR42TD
-Furrion RV Tankless Water Heater - Gas - Auto Pilot - 60,000 BTU - 18" x 18" Door - White # FR68SR
Any big trips planned with your Winnebago this fall/winter?

Hey Fred, how did the Furrion tankless water heater work out in your Winnebago? Did the 18 x 18 door line up well with your cargo bay vent? Your update could make it easier for the next person replacing an old Atwood unit.
