Stock is only a 1 way starter remote (you have no idea if it is running) and the operating range is very short. It will only run for 10 minutes unless you hit the button again to add 10 minutes to whatever has already ran.
Aftermarket offers a 2 way remote (it tells you that it is running) and you have a much longer remote range. You can also adjust the run time.
Now the one cool thing with the stock remote start is that you can now use a smart phone to operate your truck from anywhere through Onstar.
