Would be nice to have all three tow 30k with each using their lowest gearing to see how they do on LONG STEEP grades.
I too want to see - Ike in summer.
Read somewhere the PSD will de-throttle under continuous duty cycle. Not sure if it's true.
Does seem too good to be true based on cooling capacity. A class 8 running continuous 475hp requires much larger coolers, and they're likely running higher efficiency than a PSD @ 475hp.
Watched a guy on YouTube he said when the Ford fan kicks on it is really loud and consumes a lot of power. Just repeating what he experienced.
Watched two guys pull a load up the Ike and the Fords time was ~1 min less than the Ram.
Also watched the same two guys pull 30k lbs down a highway for a fuel economy test and the Fords fuel economy was 1.8 mpg better than the Ram.
Just repeating what they experienced.
