alt Hacker News> The frame, axles, brakes, engines, towing, payload hardware etc. are all lighter duty.
I have 2 questions about this:
* are you actually, really, sure? (Is this hard data?)
* does it matter when it's never going to go off-road and rarely strained (e.g. for towing)?
Yes it's lighter duty parts. If you don't haul or tow, then there's no need for a truck.
