Great breakdown of tow vehicle towing capacity by make/model

FACT: On this page, Ford's and Ram's three-quarter ton truck's awesome diesel engine and transmission power combination is robbed by rear end gear ratios of 3.55 and 3.42, respectively. Only Chevy/GMC supplies a respectable 3.73 gear ratio in their three-quarter ton truck. - See more at: http://fifthwheelst.com/2016-three-quarter-ton-truck-towing.html#sthash.mHGVdTS6.dpuf

After reading this I wouldn't trust anything these bozos say. Obviously they either don't know what a transmission does , can't do math, or don't bother doing any research. Fact- The Ford with a 3.42 rear axle actually has slightly better gearing for towing than a GM with a 3.73 rear axle due to transmission gearing.

Can you provide some links to supporting documentation that proves "The Ford with a 3.42 rear axle actually has slightly better gearing for towing than a GM with a 3.73 rear axle due to transmission gearing"?

Has not the rear end gear ratio always been the final torque factor in transferring torque from the engine and transmission? No matter what the gearing is in the transmission, will it not work harder when applying torque to a 3.42 than a 3.73 when towing or hauling the same amount of weight? Will the engine not run a higher RPM when the transmission has to be in a lower gear to tow or haul with a 3.42, with the same amount of weight, than if the rear end is a 3.73?
