I have a 2010 2500 and pull a 5th wheel. I am looking at buying a 2016 2500 but it sits three inches higher than my 2010. The Ram dealer is telling me that my 2010 has leaf springs which it does but he claims that the new style suspension on the 2016 will sit down more so the difference would be small. I am wondering if he is filling me full of bs to sell a vehicle or if this would be true. BTW the 2016 does not have air suspension.
