I switched out about every bulb inside our Class C to LED. I'm not 100% thrilled with the ones I picked out. They of course are dimmer than the original ones. Someone mentioned about switching only half of them. I got them because I figured we would be dry camping more. I ended up buying three little LED lanterns (one for each of us). We actually use those more when dry camping than any of the lights inside the RV. I may switch them all back to their normal bulbs and just result to using the little lanterns. If I feel we may need to use more overhead lighting, I can switch them out as needed.
