2015 Yukon XL
I have a post about TV selection, and I still plan to purchase a heavier TV at some point. That being said, I am toying with the idea of picking up a travel trailer in the neighborhood of 4730 UVW/68...

After looking at my RPO Codes, our Yukon XL has an interesting mix of towing features...maybe they are standard? We have the 3.08's (GU4), Rear locker (G80), heavy duty engine oil cooler (KC4), external tranny cooler (KNP), and HD trailer provisions (Z82), but no Heavy Duty trailer package (K5L). Does anyone know if the only thing I am missing is the 3.42 and IBC options? Or would there be several varieties of the oils and tranny coolers?
