Maybe it is not the outlet at all. Some Atwoods with Atwoods electric heating element came with a switch on the back of the water heater that had to be on. Then the RV manufacturer further complicated things many times by installing another switch usually in the wall somewhere close to the kitchen counter or they put it on the front facia of the kitchen cabinets. So you not only have breakers and an outlet to checkout but possibly 2 controlling switches.
I checked the switches they are working
