See if this helps:
6.0L Powerstroke Injectors
If we take your word on maintenance being done properly, that rules out oil changes and fuel filter changes.
The second cause is bad fuel.
Then perhaps you ran out of fuel and damaged injectors?
Low fuel pressure?
The list goes from there....
We have no way of independently verifying what you tell us.
Good luck ---
I would pay for an independent cracker jack 6.0 tech to go over your truck as bpounds suggests.
What causes 6.0L Injector Failure?
Besides design issues, the #1 cause of 6.0L injector failure is poor maintenance! Because engine oil at very high pressure is used to operate the injectors, keeping the oil clean is absolutely essential to maximum injector life. Extended oil change intervals are deadly to 6.0L fuel injectors - unless you are running a good bypass filtration system. We highly recommend the FS-2500 bypass oil filtration system if you are intent on extending the life of your injectors.
Besides keeping the oil clean, fuel is the next major issue that affects 6.0L injectors. Poor quality fuel with water or dirt in it is absolutely deadly to your injectors. Also, because the fuel actually provides a cushion for the internal valving of the injector, anything that causes low fuel pressure will kill the injectors. This includes not observing proper fuel filter maintenance. We recommend that fuel filters be serviced at 15,000 mile intervals. Low pressure caused by a failing fuel pump can cause repeat injector failure. ALWAYS check fuel pressure after installing new injectors. Use manufacturer's spec for your truck, but generally look for around 65-70 PSI with the engine running. Finally, running a 6.0L Powerstroke out of fuel is deadly to injectors! On early trucks, if you run out of fuel, you will usually be buying 8 injectors. If you think you are going to run out of fuel, stop, shut the truck off, and walk. It may save you $2,500. Later trucks have a PCM strategy which limits pressure to prevent injector damage during a low fuel condition, but it is still a situation to be avoided at all costs.

I am glad to see somebody is happy with Ford service.
The Walnut Creek Ford I used couple of times -dropped a clamp into my intake and denied responsibility for destroyed turbo.
Than I just got result from oil lab. The Motorcraft oil after 5000 has the same characteristics what Rotella after 10,000.
No more Motorcraft for me.
Than I don't think hauling heavy trailer is putting much stress on flat lands. Where I drive -I have 5% grades going for up to 14 miles, so even with mid sized load my F450 drives on lower gear with WOT for long time. Than there is a reason why the 7.3 PS I have is primarily choice for lot of heavy haulers.

How fast are you running the engine? I can't help but think that high RPM with those 4.30 gears can not be good for the injectors or anything else for that matter. We've had a lot of problems with our 6.0s, but I think a lot of it is running it over 3000RPM a lot.
