In the semi truck world, we only promise a max 30 degree drop in temp. Warranty wont cover repairs at that level.

Maybe because all vehicles basically use the same refrigeration cycle? It’s not totally irrelevant. I’d check mine for ya but it might be a week or two before I’m on the road with it again. But I don’t have any complaints with the A/C in my ‘19 here in a Houston summer. Cooled seats are a plus.

While the type of refrigerant (Freon is a specific type) is relevant in determining condensing and boiling pressures and temperatures all automotive air conditioning systems I’ve dealt with in the last 45 years used the same thermodynamic cycle.
Sure, vehicles are different but the A/C system is essentially the same.
It sounds like you need to rephrase your original question. You need to find somebody with the same cab configuration, trim level, exterior paint color and window tinting driving in the same ambient temperature and relative humidity conditions for a comparison. Since they put the same A/C in a white regular cab as they do in a black crew cab the rest of us are going to be entirely different...

Here some data relevant or not. 2017 4Runner blows 44F, I could trick to blow colder if I dropped fan speed to 40F. 2017 F250 6.7 (44F idle, freeway) I tried to trick it to go colder by dropping fan speed but as soon as it got to 43.5F it would cycle off to get back to 44F. 2001 lexus gs300 38F. Houston texas 95F, 50% humidity
