It was emmissions that retired the 6.0. Not that anybody was complaining until they got a 6.4 then had problems of other sorts.
I'm not throwing rocks I'm just mentioning that alittle research and you can find an awsome truck that'll fit what you need. Be it a diesel or gas.

I would really like to see your source of information. A lot of the 6.0 is in the 6.4. They bored the bock kept the stroke canned the fuel system went with a high pressure common rail dual egr coolers etc. The 6.0l was retired to meet emissions. Plain and simple. Ford wasn't even close to bankrupt. In 09 Ford bought navastar out of its contract. Project scorpion had been around for awhile. Ford had plans of going to an inhouse engine.

This is from Mike Harrison, the chief engineer for the 6.2L engine. It's the 10,000+ GVWR trucks that are de-rated on paper, but this is only due to the requirements of how they have to certify the power levels over 10,000 lbs.
Yours is rated for the full 385 HP, and the DRW trucks look like they make less power on paper. But they are the same engine; all 6.2L engines make 385 HP.
It's confusing, and we can blame our Government for that.

Just to close the loop on this, check out THIS POST.

More inportant the point I was making holds true. I notice on that page you linked that Mike mentioned a trip w/ the 6.8 and 6.2ls. The 6.2l having higher revs. What I've noticed w/ the 3.73 rear is the gear search and of course that brangs higher rpm. The 4:30s sure helped there. The 6.0ls get away w/ the 3:73s because of the tq. Just like the 6.8l rear gears will make the difference.

There is much more to engine ratings than the peak HP it can perform.
I read the story about CAT engines used in last decade widely from fire trucks, via semitrucks to diesel pushers.
The same engine could be rated at 380 HP in fire truck and 300 HP in diesel pusher.
What's the difference?
While fire truck really need peak HP for very short periods of time, it is having front radiator with good cooling. Even if it overheats for 3 minutes, it will get to the accident site.
In diesel pusher cooling is much harder to manage and those heavy vehicles can on CA 12 miles grades have gas pedal floored for 1/2 hr at the time. Manufacturers program the engine for lower output to protect it from stupid owners.

Yes but in this case they are the same engine with the same power. They just took the specs at a lower rpm for the EPA thing. The engine still revs up to the same redline as the other engine with the same peak power.

correct me if i am wrong but didn't ford use the 6.0 in their vans past 07. the mechs got the problems worked by the end of 05 and the 06 models had the best record of all ford engines pertaining to warranty work. the 6.0 got a bad rep to begin with but now they are great engines.

Are there certain years for the V10 or 7.3L PSD that I might want to shy away from? I did find an 03 7.3L crew lariat with 148K that I am going to look at this week. He's asking 13.5...bone stock.

To be honest. I really don't think so. If its an earlier than 03 v10 I believe I would go ahead and pull the plugs and get that out the way. Just to make sure everything there is done right. The first 7.3s had alittle trouble but they got straighten out. The 03s has the best power rateings for the 7.3s.

What year is the 5.4 you have been towing it with?
