At that mileage, I would go thru the starting systems real well. chaeck cables, Batts, Glow plug relay, ICP, IPR, Fuel bowl o-rings, plus more..
If you ever experience a start and die with a cold engine, I would be looking for a fuel leak or a bad o-ring. Air intrusion will keep you from starting if it is bad enough. It will also cause power and MPG issues.

Congrats on a nice truck!!!!!!!
I recently sold the '99 F250 SuperDuty (7.3L) that I helped my son buy. I payed cash for it.
(He didn't make the payments to the First National Bank of Dad, so, I repossessed it, drove it some, then sold it.)
That 7.3 PowerStroke is a beast. LOTS of power.
I do miss that old truck. 236,xxx miles on it.

Another common issue on the 7.3, leaky up pipes and warped exhaust manifolds.
Look for black soot on the firewall behind the turbo, if they are leaking replace with Dorman bellowed up pipes. If the manifolds are leaking have them decked at a Machine shop. They don't use gaskets.
If they are leaking it won't hurt anything other than down on power and a little down on mileage (big decrease in towing mileage). And maybe pretty smokey when you get on it.

depends, what gears you have. Also, the best thing on the highway is to stay under 2000 rpm to get the best mpg. Like said above if the up pipes are leaking the could cause the lower mpg, also check you exhaust pressure sensor and tube on the front of the engine to see if its clogged. could help mpg a little too. The BEST tuners are either ts 6 or hydra, looks like people lean more to hydra. That will greatly increase the performance of your truck and get better mpg. On my 7.3 f350 I had 4.10 gears with 35x10 tires with a dp tuner, on the highway the highest I got was 18ish average was 17

For the sensor location. its on the front left side, this picture will help you find it. If you go on google or even here people have threads and videos on how to check and clean that sensor.
