Is there an AC plug where you want to put the TV or did they only install a 12V receptacle at the TV? If there is an AC receptecal make sure it's powered when you're not plugged into shore power.
Yes, it sounds like you'll have an invertor, but usually not all of the AC plugs get power off of the invertor. Per the above question, if there's an AC plug at the TV, is it one of the AC outlets that's powered off of the invertor.
You may have to decide if you want to run an extension cord from an invertor powered AC outlet to where the TV is. If you can get AC power to the TV, then buy your own.
