So you are saying that if a 6.7 Powerstroke had to run at 2500 RPM to keep a load at speed you could do it at 3250? HAHAHA!!! That's funny right there. You need to get out more. I have driven plenty of 5.4's in my time and although a great long lasting engine low end power it does not have. You might be comparing to a 6.0 Powerstroke , that I would believe but not todays oil burners. You would be lucky to only turn 30% more than the 3.5 Ecoboost.
No, I didn't say that. You said that. I'm towing an 8500~lb travel trailer. Around the southeast, I don't see more than 4200rpm where my previous Cummins powered Rams saw 2900rpm. The 5.4L actually tows faster up the hills than my '03 250hp Cummins Ram. FWIW, I run 2000~rpm 65mph in OD on the flats with the 5.4L F250. Any hill will put it in direct at 2700~rpm. Steeper hills we pull in 3rd at 3800-4200rpm 60-65mph. All relatively quiet. My '98 12v 5spd/4.10 ran 2500rpm at 70 in 5th towing or not. There was no upshifting or downshifting possible with it. Sounded like a shop vac 10 hours a day. An F150 HD with 3.5L Ecoboost would do a fine job with our travel trailer. I've never owned nor would I ever own a 6.0 PSD. I have no desire or need for one of the newer diesels. The 5.4L is a long way from retirement.
