Twodownzero and ticki, you two are sufficiently showing your ignorance for things mechanical, like, say, trucks. And that's ok. Not everyone is mechanically inclined or a mechanical engineer, but where it gets tiresome is impressing your uneducated opinions on others as if it is gospel, or as if everyone else not believing the same as you is somehow endangering the health and welfare of all who come near them.
My dad used to say "it's better to keep your mouth shut and look a fool than to open it and remove all doubt."
