I currently haul a 2005 lance 821 (around 4000lbs loaded) on a 2004 dodge 2500 short bed. I am thinking about upgrading to a 2016 or newer dodge and noticed that they went to a coil spring in the rea...
Not to gang up on you but I agree with the others. You already know you're carrying 2 tons. Instead of going with a 2500 and asking what mods you'll need, go right to a 3500 and see if you need any mods.
That is unless there are reasons you can't go with a 3500.
