Ohhhh, I see the problem: you don't know the definition of the word "fact". Let me help you. A fact is when something is proven to be true by supporting evidence. It's a fact that Dan ran his last truck around in 6th gear at low RPM, and had both the engine and transmission last around 100k miles. It's a fact many of us have put tens of thousands of trouble free miles driving this way.I'll leave it at this since many of y'all are getting upset hearing facts. Engines are not meant to be lugged around in high gear below 1000rpm
And we all know gas mileage and our trucks don't add up. Y'all need some Furd Rangers or something. I can't see how you guys can put this on the forum for newbies to read and think driving in 5/6 gear at 600 rpm is proper. They'll be asking why is my engine, tranny and rear end bucking and falling apart! Really guys, I don't care who you are ,until I see one of y'all driving on video with a 24' trailer with a truck on it, in 6th gear, from the stated 600-1000 rpm, I call bullshit. If your going downhill the entire time its a little more plausible but I wanna see a 5 minute video of you superheroes pulling a 24' loaded trailer on flat land in 6th at 600 rpm! Are you trying to kill your truck for .2 mpg increase??? Dayumm I'd hate to have one of those trucks and unknowingly y'all have ride them hard and put up wet.
Have a great day and carry on.
Not a fact would be, "Engines are not meant to be lugged around in high gear below 1000rpm". That's an opinion that you failed to support using evidence.
