This is going to be another "Love - Hate" thread... Usually ending when the name calling gets too out of hand for the Moderator to put up with...

Let me begin... I loved the power of my diesel, more than any gasoline engine I have ever used. I hated the extra maintenance costs, and after a while I realized that the trade off was not worth it.

Let the fun begin!

Although I'm happy to be getting pretty much the same MPG with my '14 5.7 QC gasser as I was getting in my '06 QC 4.0 V6 Tacoma - city, highway, and combined, I have no intention of disagreeing with the OP or the link.

No hate here. But Diesel trucks can be pretty spendy and I got a deal I could afford on my Hemi.
Even considering I have never towed with my truck I'm still seeing reports of certain Diesels getting substantially better MPG under all conditions.

Yes. My 2019 3500 Laramie dually with the High output Cummins can get 17 mpg at 70 - 75 mph. Of course, that's highway, empty. Not bad for such a huge and very heavy truck. I love the sound of the newer 5th gen Cummins. It's civilized.

I liked the thoroughly uncivilized sound of my '02 Cummins HO. It pulled like the proverbial freight train in any weather. (No EGR or DEF nonsense either.)

BUT... once we got rid of the slide in camper, the ride of the 3500 got old.

A 1/2 ton gasser suffices for what I do nowadays.

I just use my 3500 dually to go to the Post Office. :grd:
