Just to throw this into the fire...
There is no different oil/ trany/PS coolers offered for the 3.7. Many have looked for different ones, no one can find any, not even a dealer.
This horse has been beaten to death.
There is extra programming included with a "Factory" tow package.
It is called Trailer Sway Control. A dealer can program this into the computers.
Some dealers refuse to do it if you install a non- Mopar hitch. But it can and has been done.
Tow group:
1. Class III Receiver
2. Factory Harness - ties into Truck's electronics for anti-sway provision/ lights
3 Seven way trailer plug with a 7 to 4 way adapter
3. Full Size Spare
4. Trailer Sway Control - programmed into the Trucks electronics.
The factory tow group is supposed to include a viscus fan, but my rig has the "tow group" and no viscus fan. I know, I know, I have a KA, but the 3.7 and trany is the same as in the KK.
The towing capacity is based on whether or not you use a weight distributing hitch.
Now back to the topic at hand. I think you should get the one that makes you the most happy.
Even if you don't tow, having the hitch back there makes for a really good recovery point if you need it.
I also agree with the folks who suggested the skids. Never hurts to ask they be included in the deal.
