Interior Slide-Out Mount - MORryde Products
Maybe your basement on your model is narrower than other models and they didn’t make the tv nook, or in 2017 they didn’t make the nook if the option wasn’t ordered.
In my 2016, I have the nook...I just never ordered the optional outdoor tv.
The tv mount is mounted to the wall that separates the generator compartment from the basement storage compartment. Then there’s another protection panel “wall” in front of the tv. So you would have a 8” or so wide nook that the tv would slide in to and be protected from your gear you carry in he basement.
I was trying to find a picture on line, but I’m not seeing one.
The tv slides out of the nook and then you turn the tv it to face you.
