I you can find an '06 or '07 6.0 and it had a good oasis report, I would not have a problem buying it.
I had an '04 F250 6.0 that I traded for an '07 F350 6.0. The '04 had an EGR valve go bad at about 35,000, replaced under warranty. No other problems when I traded it at 53,000. The current '07 had a cam sensor go bad at something over 50,000, replaced under warranty. No other problems with it either.
Both trucks completely stock. No programmers and none of the supposed "fixes" to cure all their ills.
As fordsooperduty said, there are an awful lot of 6.0 owners who are very happy with their trucks.
My best friend had his 6.0 purchased back by Ford with about 10k on it. The 3 others that I know about all 3 of them got a free Platinum Warranty for Free from Ford. Of those 3 mine lasted for about 35k before I got rid of it and my dad got rid of his at about 50k. It doesn't matter if something is free if the dang thing is in the shop every 2k miles for a few days at a time.
People have always loved to hate Fords. No matter what, if it is a Ford they hate it. My 05 and camping buddie's 03 have both been great. (The only two I have first hand knowledge of). If all the internet stories were true you would see them all along the interstates. I can't recall ever seeing one.
I have pulled into two separate rv parks that had upset 6.0 Ford owners. Trucks were getting 10k repairs. Both trucks were stock under 100k miles. Spent their vacation waiting on truck repair. Friend was a Ford mechanic at a small dealership. He spent most off his time repairing stock trucks. Not always under warranty. Why chance it? Search here on rv.net. Search Google.
Well, I can see from many of the posters, that they are pick-up only folks. I had a Suburban, and I have currently 2 Excursions. I bought my first Excursion because in 2005, the Excursions were being discontinued from all the bashing they were getting for being "non-green" and unhealthy to the environment, since they were the "Biggest".
2005 was the last year of the Excursion, so for those posting to get a 2006 and later 6.0, He can't. Ford didn't make them any more.
My 6.0 pulled my 7665lb (dry) 2001 Nomad 308 fantastically. Especially when compared to the 1994 Suburban 454 that I pulled with before. I have 4 kids and sometimes my Mother-in-law lives with us, so a 6 passenger truck only works when someone is gone. I needed seats for at least 7, and needed a way to tow. The Excursion fit the bill, and the V-10 wasn't as economical in 2005 as the diesel. Fast-forward to today. Had I known about the 6.0 Diesel today, I would have bought the V-10. My current 2000 Excursion has the V-10. It doesn't pull the Nomad as well as the diesel, but with the difference in Gas and Diesel prices, and the very minimal problems, I like it better. My 6.0 had the turbo replaced with only 50 miles. It made it another 1500 miles before the Turbo Hoses blew off pulling a mountain pass. Then at only 30K the turbo vanes froze up, over-boosted and blew the turbo hoses and the plastic plenum. It was fixed under warrantee, and has not been any more trouble since. but since it now lives with me on an island in the pacific, there is not enough roads for it to stretch it's legs, and do what a diesel is supposed to do, give good power pulling, while giving decent fuel economy. My 6.0 is all stock, and the truck is my baby...
See pics here...OP's topic on a 2001 Excursion
As I see it, there are two other options that you have not explored...
Several companies including Quigley still convert the E350 vans to 4x4, and at least last time I checked you could still get the E350 with the newer diesels.
The other option, is one that I saw here on Kodiak Island Alaska. It is a 2001 Dodge pick-up/suburban.
Someone took the time to do the body work to graft a suburban and a Dodge together using the 92-99 Suburban roof and rear windows to the Dodge bed and chassis. They married the GM back doors to some modified Dodge PU front doors, and stretched the cab to accommodate the Suburban length. I will try to take a picture of it, as when you see it from the rear, you say "nice suburban, but something looks different" Then from the side you say "that is a nice Dodge quad cab with canopy" till you notice it is all one body, then you say "WOW!!!!!"
This one is on a 2001 1/2 ton, but it would be just the same on a one ton Cummins truck... Just a few other thoughts to think about.
I do agree, that the Big three have dropped a sliver of their market, by not offering a Diesel powered Large SUV. But I guess with smaller families, my family of 6-7 is not in the "general-public" and so the Big Three do not think we are a big enough market to worry about...
IF I didn't own one now, and were in the market for a Large SUV for towing, I would give serious consideration to a 2005 V-10 powered Excursion. If it is going to be a primary hauler, you can still find low mile V-10's for much less money than a diesel, the maintenance costs are less, and the repair costs are typically less too. The fuel mileage difference between the 6.0 towing and the V-10 towing, is not terribly different, and with the larger divergence between Gas and Diesel, it may be just as cost effective to find a V-10 Ex. I have watched the prices of the V-10 Excursion drop right out the bottom compared to the Diesel ones.
Just more food for thought....

The 7.3 L (444 CID) Power Stroke was replaced by the 6.0 L (365 CID) midway through the 2003 model year. The 6.0L Power Stroke was used in Ford Super Duty trucks until the 2008 model year but lasted until 2009 in Ford Econoline vans (Model year 2010). The engine has a 3.74 in (95 mm) bore and 4.13 in (105 mm) stroke creating a displacement of 365 cu in (6.0 L) or 5954 cc. It utilizes a variable geometry turbocharger and intercooler, producing 325 hp (242 kW) and 570 lb·ft (773 N·m) with an 18Ʌ compression ratio, with fuel cutoff at 4200 rpm, but having a redline of 4500 rpm only attainable with aftermarket performance programming.
Some of the 6.0 L Power Stroke engines have proven to be problematic,(2) and speculated to have cost Ford millions of dollars in warranty repairs and buy backs. They led to many recalls and the repurchase of at least 500 trucks, particularly in the first year. However, aftermarket parts (e. g. redesigned EGR coolers) exist to address these issues and, with them installed, the 6.0L engine's reliability improves greatly.
In 2007, Ford Motor Company sued Navistar (the maker of the 6.0L power Stroke Diesel Engine), claiming that the 6.0L Power Stroke Diesel Engine was defective and that Navistar had failed to pay its portion of warranty claims filed by Ford owners and lessees.
I love this. Everyone bashing them says my friends buddy, or my dad friends buddy, or some guy at a campground had tons of problems. Very rarely do you hear "My 6.0 was a POS". And if you don't think the duramax and cummins have problems your crazy. I have had all 3 and they are all a POS.
