the psd is geared different yes. the tach is about 3000 on the highway in fifth gear going 65 mph. i hope i notice a difference in pulling power and up hills. it took all the gasser had to go up a hill.

when it comes to whether your truck has the power to pull weight up a hill, the truck doesnt care if the weight is in the bed, on a trailer, etc. would you question whether the truck would tow 6k lbs? probably not. i routinely pull over 10k with a 5.4 gasser with no problems, and i can tell a big difference in it and my psd. and i think everyone in here would be in agreement that you will have zero problems with a lack of power pulling 6k lbs. id be willing to bet you wont even have to downshift......

The truck must be a torque monster!
I hope most of your time/mileage is spent in the streets.
At 3K rpm at 65 mph out on the interstate it is going to drink
fuel like a SOB.

Huge difference.....aside from feeling all the bumps one extra time due to the trailer, you won't be able to tell the trailer is back there. I use to pull my car hauler with a 5.7L 32v Lincoln Navigator and just switched to a F-350 Dually 7.3L Turbo Diesel. Man what a difference. The mileage is a big benefit with the diesel....seems to be getting close to 15mpg while the Navi would drop down to 7-8 mpg with trailer. The Navi would have to be left in drive, and I couldn't use cruise because it woukd shift in and out of 3rd all the time. With the F-350....I put it in 4th gear, set the cruise, and literally relax

--Are You Saying Your Psd Has More Power.
without a doubt. my 5.4 is faster off the line and accelerates better at highway speeds, when both are empty. but the gasser starts slowing down a lot faster than the diesel once you start putting weight on it.

I agree I had a 99 f150 with the 5.4 in it. I actually had them both at the same time and was able to race them. The 5.4 deffently beat the PSD but put a load on them both and the PSD would come out first.
