7.3 was in IH trucks before it became the 7.3......it was called the 6.9 Yep, the 7.3 is the finest diesel ever put in a Ford, though I have no experience with the new 6.7. I know for a fact that the 6.0 and 6.4 were horrible mistakes, with the high pressure oil pump being gear driven off the back of the crankshaft??????????? That, and weak head bolts are why it is 'recommended' that the cab be removed for service.
Now, back to the original questions. An '01 7.3, you'll be fine as long as you don't overload it, the stock automatic can't hold up long if you continually drive it fully loaded. Keep the filters changed, this includes fuel and air filters. You may run into issues with the glow plug system. The wiring harness for the glow plugs runs THROUGH the valve cover gaskets. The connections get oil soaked and brittle, and will eventually wear out. Other than that, drive it.
Now, since everyone else threw their 2 cents worth of opinion in, here comes mine. Find me a 5.9 Cummins hooked to that Allison, put a Ford crew cab around it on a GM suspension and brake setup, and that would be my all time favorite, until of course AMC makes it's comeback with full sized Jeeps

what good is huge power potential when the reliability isnt there? the 6.0 and 6.4s may walk all over the 7.3 when it comes to ultimate power output, but if you are constantly fixing the engine for one reason or another, then all that power in useless.

I've only heard this recommended for the F150 gasser Tritons of the "Heritage" era. Maybe the later models called for this, but it's never crossed my mind to buy one. Cam phasers, yo.

Intrenet sources indicated that mileage is about 17-18 MPG without a load. Some people claim that they get 19 and even 22 MPG. Anyone have any experience with mileage in one of these?
You weren't looking hard enough, because most any Ford truck forum will make you a comfy home for your truck advice.

Quite easy to find service for, the trans are rather solid, and I do know that the camshaft position sensors and the harness are known trouble spots.

I won't completely call BS on the MPG claims of those sources, but my friend had a 7.3L 2000 CC and a 2001 CC dually and both got 10-12 MPGs, no matter what. But, he ran them on used trans fluid and whatever other burnable stuff he drained from his salvage cars he pulled from auctions and I couldn't massage anything more than that from them when I drove them, either.

Ultra-Low Sulfur Diesel will not be friendly to diesel MPGs now.

As for modding, well, you'll severely limit reliability unless you upgrade the drivetrain behind the engine. That includes chips because you won't stop there.

I did not buy it. It sold for about $6500. I may have missed a good deal. However it was apparently used by a company for plowing. The assets of the company were being auctioned off and they had four trucks: all ford, all red, all with snow plows (the one I wanted was the only one with a back seat). That puts a lot of strain on a truck. It had 125,000 miles. That is a lot of miles for a truck being used by a company for plowing. Probably not many freeway miles. Finally the interior was pretty beat up. It was a lariat, so it was fancy, but really worn. I will keep looking, but I will keep my eyes open for a 7.3 diesel. Lots of company auctions include F-250s. Lots of companies are going out of business so these acutions happen almost every week. 5-6 of them each eyar have trucks.

Thank you for your input.

In IH vehicles, the 7.3 is called the T444E. The POS 6.0 is called the VT-365.

We have about 800 7.3s in our rear-engine International school bus fleet and they've been great. We have about 100 VT-365s that are total junk. They're so bad, that we've bought the DT466 and it's successor, the MaxxforceDT in all new buses since. Even at 8 grand extra per bus, it's been worth it...
