Hello, I am looking for a replacement for the RV water tank and heater. The model is G6A-8E serial # 96220 334201. What we can use or do you have that one in stock? Thank you

We do carry the Dometic RV Water Heater # DMC74FR which you could use to replace your Atwood G6A-8E 6 gal RV Water Heater, but I highly recommend switching over to a tankless system like the Furrion RV Tankless Water Heater 60,000 BTU # FR98SR. This unit features a heating capacity of 13,000 - 60,000 Btu, well above that of your Atwood.
It has similar dimensions at 12-5/8" L x 12-13/16" W x 19-3/16" D so you'll need to make slight alterations to your cutout hole to fill in the gap but the performance output of this unit will be worth the work.
The on-demand hot water and ability to set the temperature to a specific degree instead of the old fashioned arrow knob will make camping much more enjoyable.
The # FR98SR has the following requirements to properly operate:
12VDC Power Input.
7.2-65PSI water Pressure (40-50PSI recommended). I recommend using a water pressure regulator like # CAM40064 to ensure proper water pressure.
11" WC - 14" WC (13" WC recommended). I recommend having a licensed technician check your pressure and adjust your regulator accordingly to ensure proper gas pressure.
If you have any further questions or need any assistance please feel free to reply back.

We also have the same water heater in our camper and are needing to replace it. As far as I know, the G6A-8E water heater is PROPANE ONLY, so how can the tankless water heater be a viable replacement? There is no power to hook it up to. What am I missing?

2 inches isn’t a little bit that’s 10% of the hole. Where is the required amps? Will it require its own electrical power 120v ac or 12v dc will be enough? What am I missing?

Kevin is the p/n an FR98SR or FR68SR? I am getting some conflicting opinions. Not at my trailer at the moment but I think the door for the G6A-8E has a 16 1/8 x 18 1/8. Much obliged!
