Choice of rear axle on 2016 F350
Hi everyone. We're ordering a new F350 (4x4 CC LB Diesel) and are trying to decide between the 3.73 and 4.30 rear axles. Presumably the 3.73 will have significantly better MPG, both empty and towing, ...

Had a 2012 F350 6.7 SRW with 3.55 and now have a 2015 F350 6.7 DRW with max tow package (wide track and 4.30). When towing I have seen no significant difference in MPG.
When not towing, there is at least a 2 MPG difference on the highway. That said, the turbo is different between the 2 so it might be part of the equation.
The 2015 6.7 4.30 has neck snapping acceleration that makes me smile whenever I put my foot into it.
