Beaver Coach sales definately stocks skylights, they even had the exact one for my 2000 Contessa and shipped it out promplty. The cost was lower than one quoted by the new Monaco that would have taken a couple weeks to receive. Changing it out takes some patience and time, but not too hard. The only thing that did not match exactly were the screw holes, but no worries, since the old ones are easily sealed with the self leveling Dicor adhesive they recommended and shipped with the skylight.
