I have a 2020 197RBS and when we were in one of the campgrounds that we visited last summer, I was out taking a walk after dark, and upon returning, I noticed that while my wife was laying in bed reading with the shade pulled down, and one of the ceiling lights on, I could see into the TT. This was after we had been using it
for a couple of other trips before. Needless to say, after it warms up here in Michigan enough to get it out of storage, we are going to be fabricating some kind of curtain to get it darker.
