I wonder if changing the geometry of these big fellas changed how they handle ? The towing is surely reduced ?

 

Trucks that have to carry heavy loads either in the bed or on the tongue need sidewall height. This means more tire and less wheel.

As for handling, anything that increases sidewall height and overall height will handle worse due to more sidewall flex and raised center of gravity; they're just not compatible.

 

Good looking pickup. Im sure it tows just fine.
