Pancho said:Nice work smartdog, but Webasto has already beat you too it. No concept phase required. Here's one of their commercial products already available that's got two sheets of glass and a big ass opening, large enough to mount a turret or eject unwanted rear seat passengers if they don't agree with your political opinions. Sorry to use a photo of the Element but it has a ribbed roof similar to the FJC, which might be an issue for some installaters.
I've found an installer here in Houston through Webasto's website. They've been around a while and are interested in looking at the FJC. I'm just not sure yet if I want a big ass hole cut into my new FJC roof. Maybe.
In my original pic, I was thinking having the sections removeable, period. That way you can remove one or both - no motors or electrics. However I am liking the accordian design. I hear ya about cutting a hole in the roof.
I am thinking that some structural reinforecement would have to be done in order to get it as big as I have it in my pic or with the Mercedes roof. (I am really diggin that roof...)
