I tow an 8000 pound trailer with a GMC 2500 with 6.0l engine, 4 speed transmission, and 4.1 axle ratio. I rarely need 3rd gear on the highway; only on steep hills. For my next truck, why not get si...

No matter how the weight compares to the rating, for a given weight, all other things equal, a higher numerical rear end ratio will put less strain on the rear end housing, the rest of drive line, and the part of the frame that joins engine to rearend.

Sure, a higher load will add more stress but...

Same here...as long as you are within ratings, the extra strain has negligible effect on the drive-train.
As long as the drive train has the correct gearing.
A 2"x4", a human arm or a gear can all handle a certain load.
However as that load increases you may need to upgrade to a 2"x6",
a bigger arm, or a stronger gear. They all have limits.
What often lost in the comprehension is that the limit is determined by the weakest link.
