Question:
We have a Forest River Rockwood with a Suburban SW10. Will the Fogatti FG26FR swap in?

Expert Reply:
Carl, yes, the 15×18 black door on the # FG26FR is meant for covering similar footprint from a Suburban and Atwood 10-gallon like your SW10. Sometimes the cutout behind the door needs a bit of wood framing adjusted, since the Fogatti box is slightly different. The cutout dimensions it requires are as follows, so you may need to trim or shim (not always): 13" wide x 13" tall x 13-13/16" deep. You'll really enjoy the benefits of a tankless heater! Less water and power wasted, and you don't have to wait to heat up!
The # FG86FR white door version works the same if you’d like white trim. Do you plan to install it yourself, or will you have a shop handle the propane line and wiring? Feel free to send measurements or photos of your setup for more clarity.
