This is what I have on my Suburban. Works great, range is okay 1/4 mile but you gotta love the 2 way remotes. I mean how many times do you wonder if you remember if you locked you door or not. And you have to walk back out and check, with 2 way you just look at remote. Plus with the 2way it sends you a sound when someone bumps your truck, or lets you know if door or hood is opened, and all kinds of stuff, like temp inside vehical and more than i know.
The Viper 5501 says 1 mile, but the price tag, on it is crazy. And I'm not sure, but just looks like a remote starter. And if your in NY you need alarm too! I see the models 5901 and 5902 have security but 6 to 8 hundred. Im sure there great systems, they say you get what you pay for. The Avital works good for me at a fraction of the price I see on the vipers. I do have a Viper secuity system only on my Firebird. It was installed by some hacks, back when Circuit City was around.
