We also run the fan in the dash to circulate the cool air since we never use the dash air.
Gasser here: I found that traveling in extreme heat, especially when going up hills, higher rpms, etc, the whole front of the coach heats up (not to mention of course the huge amount of heat radiating from the front glass and windows) from the engine heat, the engine cover inside radiates heat, also I had my shoes off once and the floor under the seats and around the pedals also is radiating lots of heat. Arriving at 3 or 4 in the afternoon, it takes 3 or 4 hours to cool down from all that heat, tires, transmission, chassis, engine, etc so that the coach is finally just dealing with ambient air temperature heat.
Dear cousin put a box fan about mid ship and wedged it in between the dinette and the sofa, blowing air up front and that did help tremendously, lowered temps up front from the mid to upper 80's down into the high 70's while traveling.
Eventually though, I had to wind up and turn on the dash a/c in the 105-110 afternoon heat while traveling.....just too much heat attacking from too many areas for the coach A/C to keep up.
