Perhaps you could borrow or buy an air temperature device, the kind that can properly measure the temps at each vent (I don't recall their actual name). At the ambient outside temps you describe, two ACs should easily keep you comfortable, and high readings would be indicative of air handling problems specific to your rig.

As an example, at 90 degrees and relatively high humidity in FL, my ACs do not run continually to maintain 72 degrees, and I have a front LR that is supposedly difficult to cool. I've made no mods to the ACs.

I recall a couple of threads about the need to better seperate the incoming air at the AC unit; perhaps someone else can chime in with that fix. I had a problem with the previous Wildcat; techs told me the ducting was "crushed" resulting in lack of air delivery, but I can't recall a single complaint about Montanas having that problem.
