I haven't done one on my truck yet, but I really like the Viper systems. I have a Python system on one of my other cars (Python and Viper are the same company) and it has been excellent.
I use a 5706 Python with a few add on sensors. It has remote start on it, if that matters or works for your application, and many other nice features. My car had power locks so I can't say much on that front. I do know that these are pretty easy to use with either aftermarket or factory locks though, you just have to use a relay to run aftermarket ones as you would for your truck
