I really like the Lance TT's, and almost bought one a year ago. One of the things I didn't like was the step-up into the slid-out dinette.
I recently looked at the current-models and do not like where they've gone with the windows. The ones I looked at were all poly-carbonate and have warning stickers all over them about how careful you need to be while cleaning them (to avoid scratches). Plus I was challenged by the opening mechanism and how the blinds worked (maybe I was having a bad day).
That 1575 is probably very bright inside for a very small TT. Watching TV isn't a big priority to us, but would want to consider if you can even see it from the dinette.
