Need Advice about this Truck...

While its pretty smokey, it does sound like typical wear of the fuel system. You could always give it a compression test just to make sure (use the glow plug holes).

Another thing to check is the glow plugs. If only 5 or 6 are working, the truck will start fairly easily, but the cylinders with dead plugs will not burn as efficeintly as the hot ones. Glow plugs are wear items, are fairly cheap, and if you go to the trouble of checking each one, it might be worth doing the compression test (just like a gasser, MAKE SURE TO REMOVE THE POWER WIRE FROM THE INJECTION PUMP!) and replacing the glow plugs.

GM used AC Delco plugs (g-90?) that would swell in the head. Don't know if the Ford glow plugs do the same. If you remove them, be very careful not to break the ceramic tip off into the cylinder or precup. If they resist at all once the threads are free, they may be swollen. Maybe someone who has doen glow plugs on the 7.3 can chime in here. Or check with your diesel shop of choice.

The fact that the PO knows about and has done preventive maintenance to the cooling system is great.

That link didn't mention anything about being a certified Stanadyne shop (I think Stanadyne was the injection system manufacture for those motors, but I'm not sure), but you could call and ask. Maybe the parts are new. Prices are great though. I might use them for my truck!

Update on this truck...

While milling around under the hood, we found that the fan moved back and forth a little when you wiggled it with your hand. So, we ended up spending the better part of this past Sunday replacing the water pump (bearing was going bad causing the fan to move). Not an overly complicated repair...cost me $70 or so.

We've also noticed that, when running, it looks like diesel fuel pools up around the injectors on top of the motor. Obviously the injectors are leaking. We figure it's the little O-ring on the tip of the injector that has failed. It looks to be about 4 injectors leaking. We plan to replace all the injectors. Anyone else on here had this problem with the 7.3 engine?

Other than that, the truck is running great. Still yet to tow a trailer with it, but look forward to it.

Had a 93 460. Sure looks familiar. IIRC you can swap the bottom half of the back seat with the front. Or keep an eye out for take off seats at a motor home or van conversion company.

Take a look at the cardin joint (front universal) on the front drive shaft. There is a centering ball joint in there that takes a needle type grease gun tip to grease it. The cnetering ball joint keeps the assembly from hangining or flopping around. I learned the hard way (and apparently the seller didn't know anything about it either) about it. It is a PITA to change the u joints in that (I've done singles, but this particular one was difficult). The problem only showed up when the right front hub was engaged.
