I've got an '08 2500, Mega, 4x4.
As others have said, get a load equalizer hitch. The ball mount they come shipped with only allows about a 2" drop. I talked the vendor in to swapping it for one with a range of adjustments that will allow more than a 6" drop. Buying this piece later is very expensive and pricy to ship, so get it with the hitch purchase.
My hitch is currently set for 5" drop but I'm sure with one of my other trailers I'll probably need to go down another inch or so. You really want any multiple axle trailer as level as possible.Less chance of overloading tires and bearings, and probably more equal braking too.
