If you are looking into the Newmar Bay Star models there is an excellent recent Youtube channel (Genesís Therapy) video that goes through in depth one of the more popular Bay Star models along with some common upgrades that he did after his initial purchase.
The video takes you through the entire coach and its upgrades providing you with an excellent and rare opportunity to see for yourself the practical use and make-up of the Newmar coach by one who used it extensively while traveling the Country before deciding to hang up his keys for personal reasons.
Having been looking at as many Newmar Bay Star videos as possible over the last 2 years myself this one was the best in depth examination of the model by far and its reference in this thread is solely intended to benefit others looking at the Newmar Bay Star models
DISCLAIMER: I tried to post the video link itself but the irv2 police took it down thinking the video was mine (lol) which would have violated the clear rules against selling your coach on irv2. Although it is not my coach, nor do I know the owner or am I even a subscriber to his Youtube channel, (not my style) the owner had apparently prepared the video on his Youtube channel for purposes of selling his coach.
We shall see if this passes muster and remains up for others to learn from since the video or link is not part of this post
