Choice of rear axle on 2016 F350

IMHO....Depends on the transmission gear ratios...
Always...the lower (higher numeric) will 'perform' better (AKA towing), but
suffer lower MPG (car attributes IMHO)...
Always...the higher (lower numeric) will have higher MPG and lower performance...
If me, I'd get the lowest (highest numeric) diff ratio as long as the tranny
has a good OD. Newer these days has double OD and why (again, IMHO) the lower
diff ratios (higher numeric) better for towing
Bottom line....decide which is more important...MPG or Towing performance
