well, we went out hooked the new to us F250 up to the TT and boy did she love to work! What a difference from fearing semis to not even feeling them go by. No white knuckling and we still need to finish dialing in our WDH... we are about an inch high up front still, we will work on that before the next tow. I do have a question for all you diesel drivers out there.... how much PSI is ok vs bad when using the engine, same thing w/ RPM's. I had heard the diesels don't like to rev the rpms on the hills like the gassers do. I was afraid to give it a push on the hills. My turbo psi gauge goes to 4 (40 psi). I got it up to 3 (30 psi) today and RPMs up to about 2000 or a little higher (not quite 2500). I have tried to find this in the owners manual and researching on-line but no good answers. Thanks for any insight.

Congratulations on the new truck. I don't know what you had before but towing with a diesel will be a vast improvement regardless.
It's kind of hard to give advise on boost an RPM without knowing which engine and transmission you have and what year truck.
If you have an automatic I wouldn't worry too much about the RPMs, the transmission should know what to do.
Most diesels make their peak torque around 1,800 RPM but can be reved to 3,000 or more without damage. The Ford 6.0 needs to be reved higher than most other diesels to reach it's power peak. Either way, 2,000 RPMs is no where near a problem and possibly a little low if you were driving down the interstate at 70 mph or so.
As for boost, is your truck stock or modified with programmers, aftermarket turbo, etc?? If it is stock, again, I wouldn't worry about the boost, the computer will manage everything.

No need to worry about that stuff for the most part... just push the pedal and go. There are so much electronics and sensors that the engine takes care of itself.
As long as everything is operating as it is supposed to, the truck will not allow the turbo to overboost (if it does, it will throw a trouble code, which means that something is causing the overboost situation).
As far as RPM, the newer diesels like to rev more than the older ones, especially the newer V8s (as opposed to a Cummins straight 6). If you're crossing the continental divide when it's 100* out, you might want to take it a little easy... otherwise, just drive it like you stole it!

True for peak HP, but peak torque is still somewhere around 1,800rpm.

It is a 2009 F250 6.4L PSD w/ automatic tranny. To my knowledge it is completely stock. We have only owned it for 2 weeks and it only has 33000 miles on it! It is running a 3.55 rear axle ratio if that makes any difference. Oh and for your question about what we upgraded from, it was an 04 nissan armada. Those that warned be about the big grin were right!
Thanks.

You can drive it to the red-line (briefly) without damage. That is what they put it on the tach for.
Fuel economy will go to hell, but the engine will survive.

Disregard all the above posts, go outside, start it up, mash the pedal to the floor and watch, it'll rev to around 3300 and no more. You can run that engine ALL day at full throttle, hook your trailer up and push the truck hard, you'll be shocked at what it'll do. Secondly, the governor on the engine will not allow it to overrev, the engine is made to work hard, thats what diesels do best. Get out there and use your truck to its full potential.

Enjoy the new truck. You will learn all the rest as you go. Do follow all the makers recommendations on maintenance, it is vital to making any vehicle last.

I'm towing with mine the first time this saturday.....looking forward to it! I'll get an apples to apples comparison of diesel vs. gas with our TT on my way out of town.....then I'll add some oranges when I come home with the new toy hauler :-)

As far as torque goes...the diesels have the market cournered. Torque is what moves your camper! If gassers are apples, your diesel is the 1000lb pumpkin at the state fair.
