My house was kind of like that. Two outlets in the Bathroom. Both were GFCI but were independent of each other.. one also fed the fan and the light.. My wife rinsed it down with the hand held shower and DARKNESS ENSUED (better the lights go out in the room then the alternative.. Don't know what got into her head rinsing down the outlet.. I used to have a "Weather hood" over it but it got lost in a bathroom upgrade.. Of course it did not used to be GFCI till after the upgrade. I put in the GFCI because the hood vanished)
I pushed the reset and LIGHTS returned.
This old house did not have GFCI in the Kitchen, only the bathroom and I installed them myself.
In an RV there are often only a few outlets and outlets near water (Kitchen, bath, Patio) are required now days to be GFCI protected.. not so in the 40's when my house was nailed together, But true today.. In both Houses and RVs
But in RV's often those are all the outelts there are.. Other than the Microwave's and Fridge's and the Washer/Dryer (If prepped and those are hidden) and possibly one or two beside the bed (optional as well) and these might as well be GFCI, in fact I'd like them to be even if mine are not.
