Recalculated with .71 transmission. I double checked and 275/70-18 tires are 33.16 not 32.6. (calculated size not acuall as it varies by brand)

All things held constant (tire size, compound, wear and manufacturer), the 4.10 rear end should read roughly 10% higher rpm than the 3.73. The 4.30 should read 5% higher rpm than 4.10 and 15% higher rpm than 3.73.
Speed should be verified with gps since SD speedos are typically 2-3% off.
Once again, rpm does not have as large affect on efficiency as load does, (more so on diesels, but a trait of fuel injection and fuel mapping nonetheless...)
