Wow - come one come all knuckle draggers....
Knowledge is power, whether you care of not, it is useful to know. But on this site, rampant over-buying, and over-spending, in the absence of reason is just how a disproportionate number of people on this site roll. That's why every other thread is about "buying more truck than you need", or buying a diesel.
And if you don't know what you don't know, then it's easier to say "I don't care" than to figure it out.
The folks in this thread are the types that reject information for anecdotes.....
