This likely won't matter to most RVs since you're staying away from the cold and snow but LEDs don't heat the lens up.
The thing most people like is that an LED uses much less electricity even when putting out more light. Downside is it doesn't run as hot. Up north when going down the road, snow, slush and ice can build up on your lens where an incandescent would be warmer and to a point melt the stuff off. Just something to keep in mind.
