TDW

But has any single F series truck (just one)  lasted a million kms or actually lasted 10 years?

My 2006 Tundra runs like a top.  I have towed my 27' bumper pull from NE BC all over the province and into the USA on summer vacations. I have no plans to replace it any time soon because it just won't stop.

Since 2006 I have had 7 company trucks, 2 Fords and the rest Chevs.  The only one that came even close to matching the Toyota was one of the Chevs.
