Proxi sensors with a viper alarm and dual battery setup. Isolate the 2nd battery for alarm only. This way the other battery will insure your truck starts at all times. Hook the proxy sensors up to your horn and lights.

That's about the only thing you can do that I'm aware of.

There was a local guy with an H1 here in Denver with those. The roof rack had the sensors setup to turn lights on all around his truck. ...cool!!!
