A couple folks in our farming region will throw a good size load on a pickup once in a while... now I do recall one instance of a pickup truck load related failure... you math guys calculate the GVWCRWARDRR on this one:
1972 F150, std cab, 6cyl 3spd, 2wd, 8 ft box. HR78-15 tires, load range who cared then?, no tuner.
Box filled with bulk fertilizer at about 55lbs per cubic foot.
Rear axle housing broke at the diff.
Shobbel party to off load, towed the truck home, got an axle from the wrecker, back on the road in 3 days. Truck run for years afterward.
