"1. Forget 12v TV's. Way too expensive and poor quality.
2. Sounds like you won't be plugged in to electric, so definitely consider an inverter and ample battery capacity. "
Saw a couple of brand new 12v Tv on ebay for around $200
I will like be living in the motor home for sometime so no shore power. I may just run the Generator while watching tv. I do have a deep cycle battery that is brand new. I replace the two house normal size batteries with one bigger size one.
So I'm guessing next on my shopping list will be a power inverter.
