Look at the aftermarket stuff. I have an Astro Flex Astro start on mine and had it on since Aug. of 98 with no problems. I have the remote start feature and love it. I lived in Alaska when I got it, and it is nice if the power goes out or I can't plug in the truck for the heating element, the truck will start by itself and warm itself up at a preset temp. The new remotes have a good range, almost 1/4 mile.
If your truck is a standard transmission Asto Flex does make a very cool one for it. It works with three lasers that can tell if the trans. is in neutral by the position of the shifter. I only have experience with the Astro Flex. I am sure others will chime in with other brands.
