23k is the best hp and NO the rpms stay the same with a manual tranny. It's gears all the way thru, no hydraulics involved. You'll know when to change gears by just listening to the motor. (don't put up the radio too loud)
bigred, we have a much larger excavator that is better if you want serious damage. We also have a collection of other Cat equipment for different kinds of destruction.
I really like going to work, I know that I am going to rip something to shreds at some time during the day almost every day. Talk about your stress relief, CAT does it good.
Thanks for the compliment on the truck, I really like it a lot more than the new ones.
Max torque is around 1900 RPM max HP is in the 3100 RPM range.
The torque is where you want to tow at to get better mileage.
Anywhere between 1900 and 2500 will be where you want to cruise at.
Pulling a big hill, running the RPM's higher with less throttle will help control the EGT's.
The diesel engine has a governor on it that will not let it run fast enough to hurt it.
The only way to over rev the engine is downshifting or going down a hill to fast for the gear you are in.
The thing that I like is the cost of insurance. I have a newer model GMC that cost me about $1000/year to insure. The F350 cost $300/year.I also have an older olds (work car) that cost about the same as F350. If the ford works out I may sell the GMC & buy a motorcycle. I could build a rack on that big flat bed to carry it. I'm tired of paying insurance.
Dave, you siad that you have done a lot of work on your truck to get it to the point where it is. What does it take to get one of these trucks to tow 20,000# ?

I grossed 20,000 with a bone stock 6.9 just like it left the factory.
Heaviest thing I ever pulled, a loaded semi with a blown clutch off the interstate.
Had to pull it up a hill to do it, he was grossing 76,000 pounds.
I was in low range 4x4 to get it going, but i got it off the road.
You have to understand, I am in the excavation business.
I have a dump bed on my truck.
It has worked very hard towing equipment, hauling stone and dirt for 20 years and 300,000 miles. I do spend a lot of money on it, but way less that I make with it.
I also am in conditions almost daily that most people would not consider taking their truck into.
How do you get 120 gallons of fuel to a dozer on a sewerline job during the rainy season?
You put a 200 gallon fuel tank in your truck bed and drive to the dozer, no matter where it is.
The mud was up to the west coast mirror on the passenger side. I had to stop and shovel some out of the way so I did not tear it off when I took this picture.
Disclaimer:
Don't try this at home, I am a professional and the truck has been modified for these and other extreme conditions.

Do you want to guess how long it takes to tram an excavator 2 miles one way and then back?
Federal scale jobs means it costs a lot of money for several reasons.
A. the excavator is not doing what it is suppose to be doing.
B. the dozer is not doing what it is supposed to be doing
C. the operators are not doing what they are supposed to be doing.
The truck is how the pipe and pipe bedding material gets hauled to where they are working also.
Oh yeah i know how long it takes to walk one that far. I sit behind the sticks of a JOHN DEERE 200clc when ever i'm not turning wrenches on the other equipment.
I said it more as a joke.
I just hate it when the operators don't pay attention to there fuel.
Wow we got way off subject!!!
I Like the disclamer

So the question is how much do you think that this truck will tow?<!-- / message --><!-- no sigs except when logged in -->
Different trucks will pull differently but my 91' Turbo (true 4" intake and full 3" exhaust) 7.3 IDI 5 OD manual with 4:10 pulled 18,000 lbs of camper, horses and trailer up 5 miles of 7 to 8% mountain pass at about 8,000 feet last fall. She never pulled less than 2cnd gear though the morning sun was up and the pass was getting hot when we reached the top with the pyro pushing the 1100 mark. If there had been more climb or if we had been climbing in the heat of the day we'd have had to have grab the granny gear to make it.
I've pulled 20,000 up shorter grades even without the turbo and I've pulled about 26,000 on level highway though I had to downshift to 3rd on even mild grades. That's just my experience but I suspect that's about the max for most of these trucks at highway speeds. The experts may get more out of them but I'm still in the learning curve. Next power upgrade will be 4" muffler & exhaust.
