So, I previously had a class C, loved the front window. I now have a 20' Puma TT, and no front window, really miss seeing out the front. I'm wondering if anyone has added a Front Window to a TT. I'm not looking for reasons not to, only reasons that mechanically would not be a good idea. I see a 20" x 60" complete setup on Ebay, wondering what harm it could cause. I'm wondering if that would lessen the roof strength OR, do the side walls and corners do a sufficient job? I'm fairly handy, thoughts, concerns.
