A:AnswerUnless you have an SUV I do not foresee this fitting in a standard size car. I have a full size truck with a tool box in the back and the Box the TV came in, standing up in the back of my truck, one end touched the tool box and the other almost touched the tailgate. I'm sorry I don't have the dimensions but I think this may give you a good idea.
A:AnswerThe TV itself doesn’t have an interface to use YouTube TV. You need your phone to cast it to the TV. Same with Netflix and HBOGO
Although kind of weird, I have YouTube TV and it does the job.
A:AnswerYes, the tv has energy star built in, I haven’t noticed any different in my bill, and if your really concerned, the tv does have a power save mode.
A:AnswerThe set is being sold in North America.
