The 7.3 is a half million mile engine, if it is properly cared for. I have owned 14 Fords with the 7.3 Powerstroke engine in them. Ever one I purchased ,had over 225,000 miles on them when I bought them. Many, I later sold to friends, and they are up around 375,000 miles now, with no major engine problems.
As long as you stick with the 7.3, anything under probably 350,000 miles is not too many, if you can verify that regular maint. has been done on it.
Be aware that the lousy 6.0 came out in 2003 model year.

Any high mileage vehicle at a good price that interests me, better have previous maintenance records or I'll walk away. Gas, diesel, doesn't matter what it is. Cummins engines can easily go 500K+. TBO is 100K higher than V8 diesels. Not to say it'll outlast, but there is a higher chance that it will due to the inline design. V8's for me are meant to be gas.

Semi's use high idle to put a 'load' on the engine so it reduces stress and creates heat at the expense of a gallon of fuel an hour to keep that engine running around 1000rpm. Idle in my old Freightliner was ~600rpm, I could adjust the fast idle from 700-1250rpm.

also realize that a semi puts those million miles on in 10 years, where it would take an average person about 6 years to hit 100k. that means that your truck is exposed to alot more age (rust, rot, ect) also breaks a truck down, compared to the semi before it would even come close to the same milage.

Tell Detroit Diesel that Diesels aren't meant to be V-8s. 8V71 and 8V92 ring a bell? The difference in longevity is built into a semi's engine while isn't on a pickups. And if you look at bigger Diesels, a million miles isn't anywhere near the max they can go.

PS : There are Chevy/GM pickups out there still running that have reached the million mile mark. On the original engine.

it's all relative to the price of the vehicle. I came across a truck when I was down in SC on a trip, that had 275k on it, with no rust and the guy was asking $1000 for it, if I could have driven two vehicles home, I would have. but had the asking price been $4000, I would have said "it's nice, but now for that money"

Try to buy under 150k, and if cared for will go at least 300k (diesel, preferably Cummins). I got 300k on a gasser Dodge for only the expense of a $19 timing chain. It was running great when I sold it.

I find Dallas, TX a great market for used trucks (no rust)

I buy, 1 owner, By owner, with records. They can go a long way. Be sure it has had some front end and suspension repairs, if not that can be spendy. (Common problem with 2nd Gen Dodge.) Trannies are also an issue. (both auto and manual) I would like to buy one that has been recently rebuilt, and service it every year (if towing heavy). I tow ~30,000 GCVW in my 1Gen (93) 12v Dodge. Very steep mtn area. I expect it to go at least 300k, I bought at 140k for $4000 (1T dually 4x4 flatbed).

I drove a '62 Studebaker Diesel Truck during college that had 3 million miles. (I did a daily 800 mile rte)
I have 300k on my VW pickup, still gets 46 mpg. I recently tried out a VW Passat diesel w/ 550k, it still was getting 50 mpg.

My truck has 250,000+. Original engine and tranny. No smoke, clean oil, good power. I got it for a steal so it's worth it for me to keep it forever.

If you can find a cheap vehicle that runs well and is easy to work on that is probably your best bet.
