OK, after reading for a couple of hours on here I am a little scared to buy a 6.4 F250. Are the regen, fuel in oil problems any better in the 2010's? I was ready to pull the trigger on monday but now maybe I should take another look at the duramax. I can get a fully loaded chevy or ford for about the same out the door price. Looking at crew cab 4x4 for farm and hiway use. ???

duramax cleans the soot the same as ford. during regen there is another injection of fuel with the exhaust stroke that feeds into the exhaust system to superheat the DPF. That in turn burns the soot.
Chevy is doing the same thing. The only time it is a problem is if you are regening and never let it finish or drive it in city stop and go traffic. I have no problems with mine at all and i have 24K on it now. I know a couple that have over 100K and no problems.
Don't forget the chevy has that luv suspension and hauling/towing are far less than the SD.

I think the biggest thing is being good about oil changes. It goes against everything you think on a diesel to have to change oil often but with the DPF and new emissions technologies you have to be good about it and seems to go for any diesel engine using this technology.
How can reducing fuel mileage while trying to clean up the air make any sense? Every gallon burned is in theory cleaner but you use more gallons to get there so is there cleaner air overall? In Ca. the air boards seem to rule and have forced us in ag well applications to either update our diesel motors to tier 3 or switch to electric motors. On 2 wells last year I went to electric and now PG&E rates are climbing! The tree huggers are killing us with regulations!!!
Back to trucks, any reason to go duramax over powerstroke? Should I wait for the 6.7?

you have absorbed the wrong information guy..these trucks have been the cat's meow..You'll miss a good thing period.
I've got 48K with no problems. I pull and plow..no tuners never will. There was a post lately with just positive reviews..and mileage..
a 2010 will be even better still.

I prefer my 2008 F250 4x4 CC much more than my previous 2008 2500 4x4 CC Duramax (got t-boned and replaced it with a Ford)......
The Chevy was nice, felt much snappier unloaded than my Ford does and got about 3 1/2 mpg better mileage but the superduty is all around a superior truck.
It rides better, tows better, feels, better, etc.....Outside of the worse mileage it is a far superior truck in eveyr way having had one of each back to back.......
Makes me wish I'd have bought the superduty first. The Duramax was nice but the superduty eclipses in every tangible and intangible criteria IMO (except the mileage).......
ALL of the big three are having "challenges" with the new emissions equipment, sadly.
I think putting an extra fuel injector in the exhaust would have been better than pumping it out of all of the cylinders. I wonder if there is something that would make that infeasible, or if it was simply a cost-driven solution.

According to internet articles, the 2011 LML Duramax will have an extra injector in the exhaust for the regen.
Those temperatures are achieved on-demand by the addition of a new fuel injector that’s been positioned directly behind the exhaust outlet of the Duramax’s variable-geometry turbo instead of using the engine’s eight existing in-cylinder injectors. Fuel is squirted into the hot exhaust and burns, quickly raising temperatures in the catalysts.
“We made a lot of enhancements to make sure the new Duramax is robust with biodiesel,” Arvan said. “The engine uses our latest-generation fuel filter that includes a coalescing filter to trap any water that could be present in the fuel. The downstream injector [behind the exhaust] for diesel particulate filter regeneration means we also won’t have a worry of oil dilution with B20 fuel from in-engine post injection [like is used on the LMM diesel].
