I agree it wasn’t the right thermometer but it measured something at those temps. It was either the vent or the duct behind the vent.
Furnace problem was simple. I turned the front furnace on and the rear one came on. The rear one turns the front one on. However they both still rely on their own respective temperature sensors. So they run on and on because the sensor in the front won’t turn the rear one off.
The front touch control turns on the front a/c and the front heat pump but the rear furnace. The rear touch control turns on the rear a/c and the front furnace.

Doug - thanks for your input. The digital thermometer I used is a Jumper digital thermometer. The “House” symbol indicates object measurement mode. It seems to be accurate with other similar type measurements. The readings I got were taken right at the vent with both a/c’s running. Although this is not perhaps the right tool to use it’s what I had and I doubt it would be 20 degrees off.
I have the mobile tech from La Mesa RV coming next Saturday to fix my reversed furnace wiring and some other things. I will have them check both a/c units while they are here. I would imagine they have a more appropriate measuring device for the application.

Front measures 42.3 rear measures 44.1 at the roof vent. It is ducted from front to rear. Same fan speed on both. Seems to be equal air flow from all vents. 3 vents in the roof in front, 3 in the rear.
30 degrees delta (Difference) Between inlet and outlet sounds like they are working as designed.
