What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Quick question for everyone real quick. I am towing my 23' travel trailer up and down the south east coast over the next few weeks and on the first leg of the trip my 2010 XL Denali is running quite hot. When we finish the next leg of the trip I am adding a TruCool 40k, and I would like to know what remedies you all know for cooling down the engine temps. They have been hovering around 220 which I know is high but not completely unsafe yet.

Stupid questions and i know you know but.....Fans kicking on right? Overflow/Reservoir is full? Nothing blocking condenser and radiator? Maybe flush and refill....

ALL fluids are less than 10k old. When the engine temp went over 210 I was worried at first so I pulled over and made sure everything was ok. I did some research an the corvette and camero road race guys say that they can sustain 230 to 240 plus but I definitely don't want to be that high.

You did 50/50 mix on the orange crap dexcool?

Changed out the AC Delco 41-110 for a set of NGK TR5IX with new plug wires. Surprisingly smoother and better acceleration with the NGK's, but the AC Delco's were pretty shot...

Need to do this bad...

The trucool should help a bunch. I added a Hayden cooler just for piece of mind and dropped 30-40 degrees. I'd make sure you don't have anything blocking your radiator. And make sure you're at the proper fluid level everywhere.
