Let's get back on topic and stop turning this into a Dodge versus deal!
I have never been a Dodge fan but a half ton diesel option could certainly change that.
A half ton really is more than enough truck for a big percentage of 3/4 ton truck buyers. Likely they buy the bigger truck for the diesel option and/or the towing prowess of the 3/4 ton. The much higher capacities today's half ton trucks have along with now a diesel option means 1/2 tons should get a second look.
I will certainly entertain the idea of buying a Dodge diesel half ton for day dirt bike trips, hauling the ski boat around and daily driver! Heck, with the torque of a diesel you can likely put nice big tires and lift without re-gearing!
