The closest Suburban-branded equivalent to the Atwood GC10A-4E would be the Suburban SW10DE (10 Gallon, Direct Spark Ignition, Gas/Electric)
- 10-gallon capacity
- LP gas with 120V electric element
- Direct Spark Ignition (DSI)
- 12,000 BTU input (slightly higher than the Atwood's 10,000 BTU)
- 16" Wide
- 15.5" High
The Suburban SW10DE has a rough opening requirement of approximately:
- 16-7/32" Wide
- 16-7/32" High
So the Suburban is slightly taller and wider than the original Atwood. In most conversions, the opening can be adapted, but the Suburban will require a new exterior access door and trim kit, and sometimes minor modifications to the opening.
