Well after only one year I upgraded to a 3500 drw. I liked my 2500 but, I love the 3500.
This truck has the 610 vs the 600. This one pulls much harder than the other. Both auto's and 3.73. Floor this one and it's gone!!!! I can't wait to put my ez and other doo dads on.
What also is very surprising to me is the ride, you can barley tell the ride is a little stiffer.
I don't think this truck will squat in the back like my 2500 did when I put my 5er to it.
This is my first dually, hope I don't forget my butt is a little wider now!!!

 

You will love your new 3500 under your 5 er. I just bought mine 3 weeks ago and like it more every time I drive the truck. We have a 9.5 camper with a slide and gen set so we are excited about taking off with it.
