Ok I’m gonna ask and hope it doesn’t get lost in the 18 wheeler braking tangent. Can one assume the same axle is used in the same model year truck and the difference in RAWR is based off SRW vs DRW configuration? I ask because the truck I’m looking at has a 3K difference between the two...

There is more to RAWR than axle.
When it is quite common the same axle is used in whole line of different vehicles, it can be coupled to different springs and different brakes.
Not to mention that differential can have several different gearings.
Common wisdom says that US-build axles can take overload quite well and several members do it all the time, while installing 19.5 wheels.
But as pointed- what about braking force?
Beside ClassA motorhomes, I did not own vehicle who I could not lock the wheels on dry pavement, but on some vehicles that can take several hundreds pounds push on brake pedal.
Not something everybody can do.
I understand there’s a lot of variables but let’s say a Ram 3500 chassis cab comes in both SRW and DRW configurations. The SRW lists 6800 RAWR and 9850 for the DRW. That’s why I’m assuming it’s the tires...
