So, the side wall in the window area is somewhat less than 1/2"? Not much less, I hope! I was wondering about that. I'm looking at the prospect of buying windows
and installing them (or having them installed) in my Hauley. I communicated with Lippert about the available interior trim rings for their windows
, and the thinnest they go is 1/2". Hmm, maybe the butyl tape will fill in the space.
