I did see that one, its on the top of the trailer which I would do if it was the only place you could put it.
But I was thinking about cutting a hole more on the side/top part of the trailer, starting at where the "vistaview" would be (if it was there) and ending where the main curve from the side to the roof stops. I think the window would have to be custom but we have some places here that can do that.
That wasn't clear in my first post, sorry.
I found a few posts on vistaview leak issues but I would expect that is more a maintenance/caulk deterioration issue.
In light of my new info, am I crazy to do this?
