I read a few of your posts and you need to understand there are tons of variables to this whole thing, How many batteries, what is there aph rating, how are you going recharge them?
And this is only the tip of the iceberg, There is a fair amount all over the internet about this, as many before you have taken this challenge on, will varying ways of doing it, but let me say a few things first; the onboard converter will "maintain" your batteries they are not really designed to really charge them (unless you make a big upgrade from stock) to try and recharge from your TV will take many HOURS nor 15 minutes to recharge, and as for the small generators that many get most do not put out much in the way of amps to recharge a storage battery. So you need to relook this whole thing back from the start and see again how much time per day of use, and what and how much battery and charging ability you have or want.
I hope some of this helps but you need to do some more homework, but in the end Happy Camping
