Why is a half ton truck called a half ton, or a ¾ ton truck called a ¾ ton? What does the tonnage refer to; is it how much the truck can carry or tow? I first learned to drive in the army at the ag...
I seem to remember, not all that long ago, that Chevy offered both a Suburban 1500 and a Suburban 2500. I'd guess that they would align with the pickups of the same number, but probably with somewhat lower tow ratings (because of the heavier station-wagon type body, vs a pickup bed). There was even a Suburban 2500 Diesel.
On the Chevy website for 2014, all they show is Suburban (no numbers) and just the 5.3L engine. Payload of 1520 (2WD) or 1580 (4WD); max trailer of 8100 for 2WD, 8000 for 4WD.
