A lot of equipment is most efficient when not straining at 100% of capacity. That's why I choose to stay 15-20% under maximum ratings. Even if a vehicle is capable of going 120 mph, I prefer to stay under that. (Damn, I am beginning to sound like my old man.)
Certainly hope one wouldn't be towing at 120 mph.....If most stay within the trucks GVWR they are WELL within specs of the truck...you don't have to be at 80% of the trucks GVWR, you still have the rear axle weight range to cover quite a bit more in most cases...So the "80% rule" isn't really needed...and I'm the weight police:)....One stays at their trucks GVWR, they're fine and most don't even pay attention to that and go by the trucks RAWR, (that's what makes me a "weight police" guy...I go by GVWR:))....
Truck shouldn't strain any more by running at it's recommended weight ranges because there is a "buffer" built into even that.....The Engineers and Manufacturers of these trucks don't want to be sued by anyone every chance they get...so there is buffer built into the trucks ratings....
