I've been thinking about looking into this just because I think it is a good idea.
First, you can put factory OEM automatic on headlights in your truck very easily. Check out my thread - Auto headlights.
Then you get into the part about having the wipers turn on with the headlights. I wonder if there are any programming options that the dealer could adjust. Alternatively, I'm thinking about looking at setting up a circuit that tricks the system into thinking it is dark when the wipers go on. Should be the cleanest install but I've haven't started looking at it.
