I just "upgraded," from a 2020 6.4 to a 2020 6.7 - it's my first diesel. So far, it's been pretty decent. Towing mileage is up almost 50% with our 11k lbs loaded trailer. I have never driven diesels - ever - so I'm curious if there are any issues with trying to run them at lower speeds. I have trouble keeping the truck at a consistent speed since I have to let off the pedal - kind of like on/off over and over - when I'm running slower that 30 MPH without the trailer. The truck has 24k miles and I never experienced anything like that with my gas 2020 ~ which I bought new and ran up to about 22k miles. Is this normal? I can of course get this to the dealer and warranty it, but before I take it in and look like a complete rookie, I thought I'd ask for some input. Thanks in advance.
