Dometic XT 6-Gallon Premium Gas+Electric RV Water Heater Review

The Dometic XT 6-Gallon Premium Gas+Electric RV Water Heater is Dometic's flagship 6-gallon RV water heater. The "XT" designation reflects premium positioning above the standard Dometic GC6AA-8E line.

Specs: 6 gallons stored, 8,800 BTU propane burner, 1500W electric element, recovery ~11 gph propane or 6 gph electric. Aluminum tank with electronic ignition control. Premium model includes diagnostic LED indicators and improved cold-weather operation.

The XT positioning targets larger Class A motorhomes and high-end fifth wheels. About $600 unit, $250-$400 install. Parts widely available through Camping World.

Right buyer: like-for-like replacement of existing Atwood XT or Dometic XT 6-gallon units, or owner of premium RVs specifying XT-tier water heaters.
