E 450 V 10 MPG

I've always stayed off the cab A/C for fear of running things too hard, hot, or just losing too much power.
Am I babying my 2013 Chassis E450 too much? *The rig is a 2014, but the chassis is a 2013*
I don't have coolant and oil temp numbers, and the coolant temp gauge has a huge dead spot near the operating temperature. I don't hesitate to use my dash aIr when I need it. The engines have reputation for very long life, some examples in motorhome duty are well over 150,000 miles. Some examples in pickups towing loads are higher than that. These people are running their engine driven AC.
The engines have an oil cooler, and a high volume clutch fan. The fan in mine runs infrequently and when it runs I know it due to the sound of the air it moves.
I wouldn't deprive myself of comfort for any hypothetical savings on the engine or AC system. FWIW I can also feel little or no effect on power from running the AC. The big deal is pulling around 11,000 lbs, not running the air conditioner compressor.
