2010 2500 Crew cab lift?
 

Hey,
I am about to order a 2010 2500 Crewcab with a standard bed. I love the chevy, but i want to put a little bigger wheel and tire on the truck. i like the way Ford has 20" wheels with an off road type tire on it. Does anyone know what i would need to have done? is it a full lift kit? I see some chevy dealers in the area are selling new trucks lifted already with 32" tires on them. I do not want it sitting like a monster truck, just so a bigger wheel and tire fit nice under it. Any help would be great.
Buy the way, what is the take on the 2500 crew cab. i am thinking 6.0 with the 3.83 rear. Should i go with the 4.10? any known problems with the truck?
thanks
