I was seriously considering a new Cummins two years ago but decided I couldn't handle the Dodge wrapper it comes in. They had the truck I wanted at the price I was willing to pay, right color, long bed, 4x4 shifter on the floor, etc. I had such a shittastic experience with my '04 Cummins I just wouldn't spend the money. After some research, I decided I had two truck options: 7.3l Ford or a Duramax (just not a fan of the GM trucks at all for some reason). EVERYONE I know with a "bulletproofed" 6.0l has sold or wants to sell it. Same with the 6.4l Ford. Everyone is dumping them shortly after warranty is up.
Just curious to watch the 6.0l process you're going through and was curious if you've regretted purchase yet or if you're still going strong with it.
I bought a V10 Super Duty as a holdover until I can figure out what I wanted and like it a lot more than expected. It LOVES fuel but I haven't had a turbo issue, EGR, HPOP, etc. The 10 mpg I get and the slightly slower towing speeds are pretty worth it so far. I do miss the badassery of the diesel while climbing hills but I'm pretty happy with the investment per $ ....
Having owned 4 superduties with the 6.0 all at varying degrees of awesome or terrible I feel compelled to reply.
My first 6.0 was a 2003.5 that ford bought back and fixed. I got a SCREAMING deal on it after I threatened the dealer for selling me a lemon law buyback without my knowledge. My dad is still driving this truck with about 150k miles on it. Ford rebuilt it at about 60k. It is super quiet, has tons of power and gets the best mileage of the 6.0's I've owned.
My next one was a turd but it had been abused by a person with more dollars than sense. Had multiple issues that I never figured out. Ended up selling it for financial reasons not related to the truck.
Next 6.0 was in an Excursion. Had a Fuel Injector Control module with bad solder joints cause me some grief. Got that sorted pretty easily then had oil cooler issues. I replaced the EGR and Oil cooler with reputable or OEM parts and it ran great. Only sold it to get back into a pickup.
My last (currenty) superduty is a 2006 F350 Crew Cab long bed. When I went shopping, I drove all three (GM, Dodge and Ford). I was convinced I would get over my Ford love and buy a DMAX. I drove several and didn't mind them. The problem I had was the cost. I like the Super Duty platform and think they are a solid chassis and body with a failure prone engine.
I created a checklist using the things I have learned from my several years of ownership and addressing different issues. I took the sheet with me to test drive each truck and I went over everything with a fine tooth comb. I ended up with a truck that had just under 100k miles for $5-6K less than a comparable DMAX at the time. I used the engines reputation to haggle with the dealer and got them down a grand and they threw in a bumper to bumper warranty for just under a grand. I have driven the truck for 25K miles and 2 years. They replaced several steering components, a turbo that was whining when purchased (part of the reason for the warranty) and a fuel sending unit. Grand total for parts was more than double the warranty. That might sound bad but the turbo was almost 2x the warranty and I knew it was bad when I bought the truck. The other parts were wear and tear items.
My truck is starting to have oil and coolant temp delta issues which means it needs an oil cooler. I'll delete the EGR and install a Ford Oil cooler for under $500 and 4 or 5 hours work.
So I think if you are a handy mechanic, you know what to look for, you replace critical parts with OEM and you run gauges to monitor things, the 6.0 can be a very affordable diesel. The other good part is the wealth of information on the web. True you have to dig and you will turn wrenches but I think that's true with any "value" in automobiles. If the only thing you want to turn is the key, you have to buy new or a toyota
FYI, I pull a 12k pound toy hauler a lot with my truck. It gets 10mpg towing and around 16 tuned empty. I love it and hope to pay it off and keep it until it is a rusty pile.
