Hi there, I was wondering if anyone has ever added a window or skylight either by themselves, or by a dealer. We really like our 09 3055 Bighorn, but it is much darker than our 04 sprinter. I was thinking a small window by the stove, between the studs, similar to the type in some of the bathrooms. I'm curious about the costs or problems that may be incurred. Another option might be a clear cover on the Fantastic fans. Mine are not transparent at all. Thanks in advance for any suggestions!
