Question:
We full-time in a Grand Design Reflection 303RLS and the Atwood GC10A tank heater just isn’t cutting it anymore. Would the Fogatti FG38FR be a good replacement?
asked by: Jenna A
Expert Reply:
Jenna and Kyle, absolutely. The Fogatti InstaShower water heater # FG38FR is the right door size (18" by 18") for replacing the Atwood 10-gallon cutouts. You’ll go from limited 10-gallon capacity to endless hot water, which is huge for full-timers. And it's more efficient since it only heats water when you need it. The # FG58FR in white works the same if that trim matches your rig better.
Do you do most of your maintenance yourselves, or hire it out when needing work done?
