If the Tow Group includes trans and oil coolers, and I really won't be towing, I may not need either cooler for a daily driver because I probably won't be stressing the trans fluid with daily driving, top quality synthetic is good oil to prevent heat shear and frequent changes of both should help combat the Phoenix heat.
I suppose if worse comes to worse, engine and trans oil coolers can always be added.
