A lot of people say that. My 06 2500HD has not led a gentle life from day 1. It spent 160,000 miles hauling 10-16K fertilizer spreaders to and from farms.
That's when I got it. It takes a pounding. Plows snow, hauls wood, junk, gets thrashed through the woods, field etc. I have gone over scales at the scrap yard with way more weight in than it should really have. 193K on it now, and the ball joints are finally showing some wear and will be replaced soon.
They did get greased every 3000 though.
I also see many construction and farm trucks that get pounded and I have only seen 1 def tank that took a hit, and the tank was ok, it broke the shield. Not to say that it cant happen, but that tank hangs no lower than any truck on the roads differential center section..
Just my observations.
