Carl; good points.
115 Deg F outside air temperature on I-10 outside Phoenix. That doesn't include the nice black asphalt, or the V10 cranking out BTUs right in front of the generator compartment. I'll guess 140 at the air intake on the genny !!!
On our next road trip, I'll put a couple temperature sensors inside the generator compartment and get some readings..
