The closest replacement to your Atwood G4-7 Water Heater 16" width x12.5" height x 18" depth dimensions is the Furrion RV Tankless Water Heater - Gas - Automatic Pilot - 60,000 BTU - 16" x 16" Door Item # FR98SR with its 12-5/8" height x 12-13/16" width x 19-3/16" depth. This will take a little bit of alteration to your cutout hole but the benefits of a tankless water heater will outweigh the initial work to setup.

The # FR98SR produces 19+ gallons of hot water an hour versus the 12 gallons a standard water heater would produce. This system provides on demand hot water and has a Vortex system mixes hot and cold water to eliminate fluctuations and reduce the risk of hot water scalding and dual temperature sensors that automatically shut power off if the water temperature exceeds a safe limit. A standard water heater has a BTU range of 10,000-12,000 whereas the # FR98SR has a BTU range of 13,000-60,000. The wall mounted controller will let you easily adjust the temperature by degrees instead of just having the standard knob with an arrow that increases in size as the temperature goes up. Overall you'll be much happier with the performance of the tankless versus your previous tank water heater.
