I have had three diesels,

First, 2002 F250 4x4 Supercab Longbed 3.73 SRW, powerful, economical, but had
a Smaller Popup camper. Excellent.

Second, 2011 Chev Silverado DRW 2500hd Longbed supercab 3.73 with an
Adventurer 910fbs, heavy camper, would have been better with 4.10 and DRW.

Third, 2012 Ram 3500hd crew Longbed drw with 4.10 and 2013 Eagle Cap 1160,
extremely heavy camper, with sway bar, supersprings, Timbrens, despite extreme
weight, uses only 5-6% more fuel, but with 4.10 has incredible power at low & high
speeds with the added stability of dual rear wheel and other upgrades.

Apples and Oranges

You cannot make a judgment on gears with these trucks. They are all different years, makes, and models. The only way to make a statement about gears is to have the same drive train in a truck that has 4.10 gears vs 3.73 gears. Now if you go out and by a 2012 Ram with 3.73
with the same drive train then you can give real world experience about the gear ratio's.

Put 4.10 gears in that 2002 truck of yours and put 3.73 in the 2012 Ram. The 2012 Ram would still blow away that 2002 truck in towing.
