"Newer" Ford trucks don't charge house batt's?

So lets push our luck that this one is granted entry to this thread too.....

Mr. Wizard: I'll not put you through further questions from a pea brain. But would ask if, since you have obvious knowledge in this area, you've seen a video or website that has a good, straight forward explanation on the how's, what's and why's of truck to TC charging systems, suitable for the rank beginner?

Much appreciated!
