The old truck was 2010 F350 with the 6.4L. Well, maybe it had more power and acceleration, but the ecoboost still had no problems getting up to speed in a hurry. I actually had to make sure that I hit the cruise control because I caught myself doing 120km/h a couple times with even noticing.
The F350 a great truck...I just got sick of dealing with diesel particulate filter. Other than the summer months, I only made short daily trips with it, so the DPF was more work than it was worth to me. I was a little apprehensive at first about making the switch (thinking it would be a serious downgrade in performance), but I am really glad I did.
