I wonder if there is a translucent skylight-type panel available for something like the Amazon vans? 
That video is from 2012, so I'm guessing it'll be never.I really like that Dometic Freshlight. Too bad they don't sell it in North America yet.
One thing I considered with a sunroof installation was making my own tapercut fillers out of PVC/ABS/Polyethylene or some other plastic. Like a large bespoke version of Hein's vent adapters.We just received the CR Laurence Autoport 15” x 30” (AP1530B5H). Haven’t installed it yet, but it looks like the curvature of the sunroof is probably going to work out OK with a little extra butyl tape on the sides. 🤞🤞
The instruction book is terrible. There are different options for the trim ring, which I didn’t realize until after it arrived, so if you want to order one, check if “universal, molded, or van trim ring” is best for your application.
