i have owned both trucks you are looking to get and would definitely go with the duramax. for a daily driver it is just so much more comfortable and i think it pulls better than the ford 7.3. certainly a lot smoother.
Tough task....I know....let me know your thoughts.
the dmax has amazing power, bolt on queen, and the allison is just freakin amazing. I've driven 7.3s and a cummins with a stick and a goerend, and the allison was just as amazing the last time I drove one as the first time. The front end isn't as weak as its made out to be, and the powerstroke front end doesn't hold up like a kingpin D60. The 7.3 is good for some miles, but if your deciding between the 2, I think the duramax is definately the way to go.
Get an LLY if you can, or an LB7 that had all injectors replaced under recall. If you can't find either, its not that bad, thats just the only problem the duramax has had. The only real downside is the $$$$ required to lift it. Power its a no brainer and with proper tuning people are pulling some crazy MPGs with proper tuning.

Yeah....the research I've done would seem to lean me that direction with the upgrades they did for the LBZ. I wonder if the injectors have been done though, if the older ones are a better way pricewise.
i wouldnt do a ford they naturally drag *** no offense 5.9Bronco... an duramax there ok i like them but watch your drive shafts an cummins is the real deal so id get a dodge just my opinion
yeah the 7.3 wouldn't even be an option to me if the Duramax is also an option, better power, better transmission, chances of still having a warranty, and best ride out there sure some will argue, but they're in denial

I would do the duramax and totally agree with you except I cant seem to find the 06 DMAX with 6-speed allison for $5 or $6k more than the Ford 7.3L which is about my cutoff....
