Tempting to upgrade the intercooler and look into a better oil cooler for both engine and transmission. There is still a place for a GMC Denali 2500hd diesel with 910ftlbs of torque. I’d love to have an old one parked out back just for towing duty. If you haven’t tried one then you haven’t experienced towing nirvana.

And no way am I turning off AC when it’s that hot at muggy. 95F in the Rockies is way different than that temp in the muggy east coast.
