We are actually starting to reach semi-truck levels of power and capability. Seriously, 35 000 max-tow isn't too far off what most semis you see on the road are pulling (40 000lbs).
Now, granted, the axles, tires, suspension, frame, transmission, and even the frame are no where near as heavy duty as a semi-truck. Semi trucks routinely go multiples of millions of kms over their service life pulling 40 000lbs+, and I doubt you'd ever see a light duty truck make it over 300 000kms pulling 35 000lbs every single day.
But still, pretty impressive numbers from a light duty truck.
