2010 Dodge Ram HD and 2011 Ford Super Duty?

I want a heavy duty truck, but i dont plan on towing much more than 5000 pounds, Its a matter of want. However which of the two trucks are more fuel efficient for diesel and gas, and how much maintenence should i be expecting on all the engine options
get a 7.3 powerstroke ford 2010/11 whichever is out diesel
it will give you the most torque and mpg's for your money
around 30ish mpg and the dodges are known for their transmission problems
butt if your gona
