Just adding my 2 cents . . .
Dan has supplied me with all the LED conversions for my last 2 campers and he's been most helpful, even to having specialty light bulbs made for the LY moho wardrobe.
BTW, Dan - the Excella is almost totally LED. What is still incandescent are the step light and waste valve light (they look like a licence plate light off a truck, the bulbs are not replaceable) and the light for the license plate.
