In my opinion, it would not be a bad thing to have GFCIs on every electric circuit in a house or RV, at least on every circuit that has an outlet or light with a removable bulb. They can and do save lives.
No argument that they are a good safety device, especially in wet areas, but the NEC does not require GFCI protection on overhead lighting circuits. You wouldn't want to be left in the dark by a random trip of the sort GFCIs are famous for.
RV lighting is 12VDC so GFCIs don't apply.
Indeed the code does not require GFCIs for many circuits, and I didn't mean to suggest thag. AFCIs, a somewhat different beast, are now required and from what I have read more prone to falsely tripping. In my (limited) experience, GFCIs are not overly prone to false trips, but ground faults can be devilishly tricky to track down.
(AFCIs are arc fault circuit interruptors and attempt to stop sparking loose connections and similar problems. Telling sparking motor brushes from sparking loose wjre nuts doesn't always work.)
