what model years can we pull from and what kind of a drop do i need and what kind of prices am i looking at

 

It all depends, Mine is a 05 CC V6 Auto ST with Tow Package
Any Year and model can tow. Others will chim in with more info.
If you are geared differently, and have good brakes you COULD tow more, but I would say stay to factory specs for safety

By drop I assume you mean receiver, Which depends one your trailer with also dictates ball size either 1 7/8", 2" 2 1/2" (I think it is) or Pintle Style
Most trailers are 1 7/8" or 2" (Most rentals are 2")

You can either buy a full hitch and harness, or a kit (Bolts to bumper support) and harness

 

Heres a pic of a factory hitch. The tube you see coming down is the bumper support. Which also doubles as the hitch. they all have it as far as I know, Just without the 2" Tube part and safety chain loops

 

as you can see from reject's pics, the factory tow package/bar/junk is frame mounted and welded on. If you do not have a factory tow package, I dont know if that tube is there and the hitch part is not or what. Look under your rear bumper, whats under there? I dont know if the 05-07 stuff will fit an 08....

 

If you do not have the factory hitch, you will have that bar, you just need to buy the kit that bolts onto it.

 

so ive been looking online and they have the reciever part by its self and then they have what looks like the bumper support/reciver which is a better bet to go with?

 

It all depends, A Hitch by itself will also add some weight, well getting the part to turn the bar into one, adds less weight, either is good. Just make sure you get a T connector for lights.

 

Of all else fails u haul installs hitches.

 

thank you for all the insight for the types and styles of hitches but i still havent figured out what model years i can pull from. is it like the third brake light and i can pull one off a 2nd gen or am i limited to 08 and newer?

 

08 was a changeover. so prolly. Man those trucks looks like they hit a brick wall.... but anyways I would stick to anything 08 and over
