Thanks k30 for the suggestion.
I had looked at the F450/550 route but the main issues I had with those for my build (being under a suburban):
1. You wind up with the 10 lug bolt pattern and then have to run commercial wheels/tires or get a turned down 22.5" rim to 22" which allows slightly more variation in tire selection. Or an insanely expensive aftermarket set
2. It does have a wider front axle track (2011 F450 DRW = 74.8" vs 2011 F350 68.3") but I'd like to maintain an 8 lug bolt pattern (whether 8x6.5 or 8x170 etc) but with having a deeper (more negative) offset will help allow for the lack of width the F350 axle provides.
Other than adding in the suburban body and a Duramax/Allison, the weight of the truck will be well down from its original >9,000 and GVWR of 15000 won't ever be touched.
Do you think running an F350 axle in general is too weak for this truck's weight to handle? A 2004 F350 ranged from 5400-6900 lbs with GVWR 9900-11000.
