The only non-tankless model that we currently offer is the Dometic RV Water Heater # DMC74FR. This heater is a bit smaller and only comes with a 6 gallon tank so it's a bit less than what you're looking for. The Atwood line has pretty much been phased out by Dometic so I recommend checking with them directly to see if they have a similar Dometic branded 10 gallon unit to replace the GCH10A-4E. view full answer...
