3 absolute truths, and 3 pieces of unsolicited advice
Name and motor vehicle available in the world and I can find 5 people who will tell it is the worst piece of engineering ever built, a complete hunk of junk and the men who designed it kick their own dogs. I will also find you 5 people who will say it is the most cleverly designed conveyance known to man, only an idiot would ever have a problem with it and anyone who complains about it kicks their own dog.
Every car company has, at one time or another, made cars that sucked. They are called lemons. We have a law about it. And t-Shirts. Order one.
Anyone who starts a forum post with the words "piece of XXXX, junk or left me stranded" is not in the mood for a spirited debate. They are extremely upset by how the universe conspired with an auto maker to cause them undue harm. Responding to them will re-enforce in their mind the pre-conceived notion that you are either an idiot, or an evil Sith Lord. Or probably both.
Unsolicited piece of advice 1:
If you have never owned a diesel truck (driving one on your Grandpa's farm "like almost every summer" does not count); don't buy a new truck. Buy a used one, preferably one that is well used and extremely cheap. Then beat the crap out of it and learn how to fix it. This is actually how people use to learn how to do things before we all got online degrees in nuclear fission from Friends University.
Unsolicited piece of advice 2:
Your brother's uncle's cousins' hairdresser does not get get 45 mpg in his DuraCumStroke pulling Mount Rushmore over the Andes Mountains. If they existed, they would still be lying. And the on-board MPG meter is more optimistic than a fraternity kid on Saturday night.
Unsolicited piece of advice 3:
Anecdotal evidence is 100% wrong over half the time. The other half of the the time it is simply incorrect.
