You would see them. I have the same engine although mine is a 150 not a 250 but I imagine it's the same. There are sort of two cats. The first one is right behind the O2 sensor. The next one is about a foot back from that. If you smell it then they are probably gone

So I changed the coolant, Thermostat and bleed the air out.
No change. Reading still in the "N to O" range. Truck doesn't suffer from anything. Doesn't appear to be over heating at all.
Just thought I would throw that in there as well.

Non issue. I think they are all like that. I don't know what temp the stat is in mine but in 100 degree heat w the ac on high she rarely gets past N and if it does it cycles back down lower pretty quick. On 80 degree days w no ac it stays below N all the time on mine. You could change the thermostat to a 195 degree one and see if that changes it. That's as close to stock as u can get and most recommend that temp anyways

OK. I have ran the tests again and all are 111.
So I am thinking mechanical. The other day after driving for awhile I got out and touched both front wheels, they were both hot. Breaks dragging? Both at the same time? I live in the hills and put the truck on a small grade and put the truck in neutral. Truck seemed to move fine but with a heavy truck I would guess a small amount dragging breaks wouldn't make a difference. And, both breaks dragging at the same time sounds weird. I had a caliper go bad on the front of my jeep but it was just one not both.
Is there a way maybe the proportioning valve is bad for the front breaks and causing them to drag?
Would my truck move in neutral on a small grade if the breaks were dragging?
I notice a small shimmy when I lightly apply the breaks but goes away when using them normally to stop. Not sure if one has to do with the other.

As always I really appreciate the info this is a great place for the shade tree like me.
